2000 Dodge Intrepid: Only heat no cold?

Only heat works no cold air.Temperature control not making any change.

On this model it has Manual temp control buttons.

It can be issue with control module itself.But there other possibilities too.Before changing any other thing it advisable to check other possibilities too.
Go through further troubleshooting mentioned below:-------


Most of the time it is due to a faulty temperature blend door actuator, but may be the blend door itself. Access the actuator and disconnect the harness connector to it. Use jumper wires from 12v source or battery to apply voltage to the #1 terminal and a ground wire to the #2 terminal. then apply power to the #5 terminal while #2 terminal is grounded. If the actuator doesnt work, then replace actuator(directions to access and replace are below). If it does work, then the blend door is bad and this unfotunately means the whole dash has to come out to replace it
The help procedure is mentioned below:----

TEMPERATURE DOOR ACTUATOR

The blend-air (temperature) door actuator is an electric motor which mechanically positions the temperature door. A feedback strip in the actuator allows the computer control to know the exact position of the temperature door at all times. The blend-air door actuator is not serviceable and must be replaced if found to be defective.

The temperature door actuator is located at the bottom of the heater housing at the center tunnel

REMOVAL

1. 
   Open hood and disconnect the negative battery cable remote terminal from the remote battery post
   Remove left and right underpanel silencer/ducts.
   Remove two screws from actuator which are accessible from the right side of center stack.
   Remove one screw from actuator on left side.
   Pull actuator straight down from shaft and disconnect electrical connection. Upon removal, note the shaft position of the actuator, because the shaft on this motor is keyed. When installing new actuator, its shaft must be positioned in the same location.

INSTALLATION

For installation, reverse the above procedures.


This will help.
Thanks.

2000 Chevy Corvette: Vehicle runs hot when A/C is ON?

Engine gets overheated hot in traffic when A/c is turned on.

But in Normal open road it works fine.

In this types of cases the thermostat and cooling fan needs to be monitored.

There are two engine cooling fans on Chevy corvette 2000 year model vehicle.


So first you do need to verify that both fans are properly  working. For that you may need to use a flashlight to see it spinning. If it isnt, then the basics of checking for power to the motor, and if no power, then checking the cooling fan relays and fuse(both labeled) in the engine compartment fuse box.

If no power at the fuses, then engine coolant temperature sensor and ac pressure switches will need to be tested and finally, if needed, the pcm tested.

If the fan is working, then first check for any missing, cracked or broken fan shroud that is allowing for inefficient fan cooling.

If ok, then both ect sensor and ac pressure switch and pcm will need to be monitored with a scan tool to see if the fans are coming on at proper temperature and ac pressure and then fan monitored to see that it is spinning at proper speeds.

I know that sounds like a lot, but with symptoms described, this is in the fan operation in some capacity and will require going thru the above steps to find the underlying cause and then repair.

This details will help.
Thanks.

1997 Buick Lesabre: A/C stopped Blowing cold?

On Buick Lesabre 1997 Year model Vehicle it has Automatic Temperature  controls with separate Controls for driver's and passenger side temperature adjustment.

In this case first the A/C stopped blowing cold at passenger side and then stopped blowing at driver side.



Ok, the automatic climate control does not have vacuum controls. The blend doors are electronically controlled by the climate control unit and actuators at the blend doors.

Hence one side stopped working and then the other, this majorly indicates that the climate control module failing rather than both the driver and passenger side blend door.

If the shop doing the work does not have a scan tool that can test the climate control unit and the temperature blend door actuators, you will need to have another shop test it or have a dealer test the system.

This needs to be done before spending money on replacing the doors when it is unlikely that both have failed at once.

This details will help.
Thanks.

How to inspect Vehicles A/C Compressor and Clutch?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

An electromagnetic clutch used to engage and disengage the compressor, to turn the air conditioner on and off.

Compressor

There are several things that can go wrong with a compressor. They can leak from the front shaft, from seals on the case, or from O-rings on the back. Sometimes, the aluminum tubing that supplies the back of the compressor develops a leak.

There are hundreds of configurations of these. Aftermarket companies produce them and have catalogs listing them by number. Some mufflers have a filter that must be replaced in the event of a compressor failure. When you replace one compressor with another, it is important that the correct one be used. Be sure you have the correct part number. On the GM radial six-cylinder compressor there are twelve different part numbers. The difference is in where the compressor is mounted. It is important that the correct mounting be used so the oil passage is in the right place.

On orifice tube systems, oil is pulled up from the bottom of the receiver dryer. If the refrigerant level gets too low or if the oil hole gets plugged, the compressor can fail. Rebuilders recommend replacing the accumulator with every compressor replacement. This is because they do not want to take a chance that the oil hole is plugged and the newly rebuilt compressor will fail due to lack of lubrication.

Clutch

Check the operation of the clutch. You should hear the loud click of the clutch as it engages periodically. Electric cooling fans should begin to run at low speed when the clutch comes on. Check wiring and hoses for obvious problems.

When clutch engagement problems occur, check for voltage from the source. Then use a jumper wire to apply power and ground to the terminals on the clutch. This will bypass the protection devices and determine whether the problem is the clutch or the circuitry. Parts of the clutch and compressor are shown below.
