CAR A/c clutch will not remain engaged

A/C clutch getting disengaged.


When the Air conditioner is turned on in the ford vehicle the clutch gets engaged,but in few secs the clutch gets disengaged and compressor turn off.

In such cases ,may be on any brand vehicle.

First measure the AC high and AC low pressure when the A/c is running.

As its said that A/C turns off in few secs.So the Ac low and high pressure needs to be tested quickly in few successions when the A/c is running.

It can be tested with AC pressure testing tool.


The pressure tells whether AC is low on charge or its faulty component issue or problem with clutch controlling relay.

On normal basis running pressure on a fully charged A/C system at idle needs to be right 35 to 40 PSI low side and 200 to 225 PSI on the high side.If the A/c pressure is  anything less that these pressure ,then the system will cause the low pressure cycling switch to turn the AC compressor off.

 If the pressure testing shows that both low and high pressure is ok. Then its either a bad AC clutch relay or the AC clutch is heating up and breaking down and kicking off.

To confirm these problem you need a voltmeter.With the help of  volt meter check at the clutch and see if you have battery voltage when the clutch kicks off, if so and no clutch action means the clutch field coil is bad and needs replaced . If no power is found then suspect a bad clutch relay.

So as per these test,you know what part is faulty and you can get the faulty part replaced.

overdrive light come on and off

The problem noticed on 2001 Ford Explorer.

The overdrive lights goes on and off on dash board.

This case is related to transmission or with gear issue.

Sometimes its just a basic warning to get the vehicle fluid level checked.

But the best possible way to get the problem confirmed is get the transmission module scanned.This will tell what problem is there.In scanning the error codes are retrieved and as per that further troubleshooting is done.

On these particular case the problem was related to faulty 2nd and 5th gear and replacing the gears solved the issue and overdrive light is gone out.
Also the present condition of transmission is not very good.So its advisable to get the transmission rebuilt by proper transmission professionals.

But the ford was running fine with same transmission,so customer was not interested in replacing the complete transmission.

These details will help.
Thanks.

Vehicle runs lean causes misfire

There is lots of thumping noise and vehicle idles rough.

On such cases the diagnostic codes received are P1151 and P1131.

Also the misfire Error codes will be  received.

P1151 and P1131 codes are for the O2 sensors are for lean concerns which indicate there is to much oxygen left over in the exhaust or not enough left over fuel. Normally this is the result of a vacuum leak after the MAF sensor. So the lean concern can be causing your misfire codes 0300 and 0316.



Try these test procedures:---
Run the engine cold. Spray short busts of starting fluid around all the vacuum and PCV hoses and the intake gaskets. When a leak is hit, the rpms will increase.


Also on some cases you will hear noise from intake
If you have a noise in the intake, there is a good chance it is cracked as well as leaking.

So inspect the intake manifold too.

Also on such cases the fuel pressure is important.So inspect the fuse pressure.If its very low or very high,then fuel system, parts needs to be inspected and replaced if checked weak.

The fuel system consists of fuel pressure regular,fuel pump,fuel filter and fuel itself.

If the fuel in the vehicle gets dirty,or thick,then it can cause such problems.Getting the dirty fuel replaced with good fuel helps.

Thanks,.

Rear End Grinding Noise While Accelrating

The rear end grinding noise issue.


At our auto repair garage we have deal with lots of vehicle with such such issues.

One more with same problem,this time it was 2005 Ford explorer.

The vehicle made grinding noise while accelerating only.Then the noise will not continue further.But these noise will always occur while start up.

So as per these types of problem already seen and noticed at our garage.

There are two possibilities,either its a issue with bearings getting worn out or the major issue is with transmission going out and needs a rebuilt by proper professional.


The 2005 ford explorers has a lot of rear end concerns, and it sounds like to me that it is a bearing going out in the rear end.
Inspect the bearing visually to confirm the problem.try cleaning the dirt collected on side of bearing first and view its actual condition,If it looks out of alignment and worn out,then it has to be replaced/.


But if the vehicle is making winding noise while going to drive mode and if the vehicle shakes a bit while start up,then it points out towards the faulty transmission.


So inspect the condition of your vehicle,as per what conditions are there,you can further go in that way,to resolve the problem.

These details will help.
Thanks,

Chrysler disk read error

2005 Chrysler Town & Country disk won't eject and gives disk read error


Chrysler with Navigation system has intermittent problem and few issues.

The issues like:----
  • The disk will not eject
  • The display shows Disk read Error
  • Also cannot change radio stations or put in a DVD while this is occurring.
Mostly the problem starts only when the DVD is loaded/inserted in the unit.But when DVD disc is not inserted then this same unit works fine.
When the DVD has been ejected, all other systems work fine - the radio, the disc changer, etc.


AS PER THESE DETAILS THE BASIC TROUBLESHOOTING DETAILS ARE AS FOLLOWS:-----

Most likely it seems like an internal radio failure issue. 
This is why because if the problem is with the disc then it shouldn't come with the other problems you are having, a bad disc shouldn't cause you to not be able to change channels, eject, etc.

YOU CAN TRY:---- 
Pop your disc out and see if it looks damaged. Check it over for any physical damage and make sure it's clean and not dirty or dusty.
If the disc looks ok then most likely it is and the failure is in the radio. If you haven't already, try disconnecting the battery for a couple minutes, reconnect it and see if that helps.This procedure resets the complete car system. If not then the radio will need to be replaced or sent out for repair.

RADIO REPAIR OPTIONS:---
Locate the used unit (reliability could be questionable), an exchange remanufactured unit through your dealer, or remove yours and send it to a radio repair facility.
Now-a-days many shops or dealers will have repair places that they routinely use, like United Radio. Sending them out to have them repaired is normally far cheaper than an outright replacement, but actual price depends on what is wrong with it.
So first get the fault detected with the system.This will let you know what the repair cost will me and then you can make your decision further.


This details will help.
Thanks.

LINCOLN TOWNCAR AIR SUSPENSION LIGHT

TURN CHECK AIR SUSPENSION DASH LIGHT OFF 

Vehicle model 1996 Lincoln Towncar

Hope these procedure helps to turn off the Air suspension light.

First of all access the Airsuspension module.For that you need to remove  glove box . The Air  suspension control module is mounted on the AC/Heater box .
The Module has black connector and a gray connector. 

Now here the actual procedure starts.
If you Unplug the black connector ,that it will turn off the "check air suspension light" but with that it will also disable your power steering tension (variable assist steering) control on the left side of the steering column. 

So to only turn off check air suspension light and not power steering control the trick is to  unplug the black connector and then you need to remove the dark green/light green wire pin from the connector (pin #11) and then reconnect that black connector to the module. That will disable only the check air suspension light. 

Also you can  just identify that black connector to the module and cut the green wire. And be sure to isolate that wire because the "check air suspension light" will come on if it touches ground.

==================

FOR same problem 2001 Lincoln Town Car Air Suspension Light will not go off

To turn the light off and disable the air suspension, you have to disconnect the air suspension module.
The module is located in the luggage compartment, exactly behind the air suspension switch.
To access the Suspension module pull back the wall carpet and remove the 2 nuts that hold the suspension module. Unplug the suspension module and bolt the module back in place.

But disconnecting the module connector will also disable the active steering system. 

As mentioned in the previous section on the older Lincolns you could cut a green wire and that would kill the light. The newer ones like this one have the suspension/steering module communicating over a data bus with the instrument cluster. There has to be some faking the suspension module out to get the light to stay off. The steering/suspension module on this year is located behind the dash. 

=================

FOR 2002 LINCOLN TOWN CAR WITH AIR SUSPENSION LIGHT ON

Is the vehicles ride height high or low on any corner?
Since no such air ride issues are noticed then it may something simple as just a corroded electrical connector or a air ride height sensor thats failing. To know whats wrong you must get a scan tool hooked up and retrieve the stored fault codes. The error code will point out what is causing the Suspension light to remain ON.
The suspension light come on if you either turn the system off or if its a problem in the system. Either way you are fine to go ahead and drive it with he light on as long as it hold ride height till you can get it in for repair.
===================

These details will help.
Thanks.
