Check the wire from the ac clutch back and look for a dead short to earth . look for pinched wire. Wire worn by drive belt etc. Any indication of where a live wire is touching earth.

SOURCE: a/c compressor clutch will not engage

There is a compressor relay "fuse" under the hood (in the fuse compartment). It is black and has a "diode" symbol on it. I replaced mine and all was well. Good luck.

SOURCE: A/C is not blowing cold air and clutch on the compressor will not engage.

Most likley needs to be recharged. Shouldnt be low, but if it has ever been in an accident it may have a leak or your mechanic stole the refridgerant when it was cold outside and you didnt notice untill you turned the ac on.

you have a short somewhere problably bad ground , or interferrance from alternaot overloading the circuit... check all ground securlely...if you cant locate it its not going to be cheap for a mech to locate the issue.. good luc kthough ( also check for loose wire behind the fuse box in car.

105 psi? If so that is way to hi...especially for a mid-sized car. You ideally want you pressure to be between 40-50 psi. If you pressure is that hi you might have blown the pressure valve on you compressor, which is not a part that is sold seperately. You should take your car to your local Pep Boys and have them run a A/C diagnostic which runs around $45 to give you an better idea. If you don't know what you're doinf the A/C system is not something you want to play a guessing game with. Especially since it's illegal to work on it without the proper tools and licenses.

Fuse keeps blowing on a/c on 2001 dodge truck


Let's break this down.
1 Does the fuse blow when the heater is on, or just the AC?
Yes- Fan motor problem likely need new blower motor.
No- 2
2 Disconnect the AC compressor clutch wire. Remove the blown AC fuse, connect a multimeter across the sockets for the fuse, measure DC voltage across the two sockets with the AC switch, and Ignition switch ON. Is Battery voltage present?
Yes- The wiring harness has a short between the output of the AC switch and ground, likely a pinched harness.
No- The AC compressor clutch is shorted. Replace either the whole compressor or the clutch.

HIGH PRESSURE CUTOFF SWITCH LOCATED ON AC COMPRESSOR DISCHARGE LINE LEADING TO THE CONDENSOR.THE HIGH PRESSURE CUTOFF SWITCH WILL CUT OFF THE AC COMPRESSOR IF SYSTEM PRESSURE RISES TO HIGH CAUSED BY RESTRICTION IN THE REFRIGERANT CIRCUIT OR OVERHEATED CONDENSOR.MAKE SURE COOLING FAN IS RUNNING WHEN THE AC SWITCH IS ON.THE COOLING FAN KEEP CONDENSOR COOL, IF COOLING FAN DONT RUN.YOUR AC WILL STOP BLOWING COLD AIR.HAVE THE REFRIGERANT SYSTEM CHECK OUT.MAKE SURE YOUR LOW SIDE PRESSURE IS 10 - 37 PSI. THE HIGH SIDE PRESSURE SHOULD BE 112 - 210 PSI. CHECK THE AC COMPRESSOR CLUTCH FUSE AND RELAY.

Ac cycles on 92 blazer ,new compressor,low switch bad?


Did you replace the dryer,and the orifice tube?If the orifice tube was not replaced,this is most likely the problem,what are the pressures while it is running,and how much freon is in the system?If the system does not have enough freon it it,it will do this,but if it does,the cycling ac compressor is because of the orifice tube,if the system was not flushed out,and there was a new orifice tube installed ,then it is stopped up again.Let me know something so I can help.

Where is the expansion valve located on a 98 Grand Am 3.1?


Grand Am has an expansion valve. Link below has part number and picture of what you are looking for.
http://www.discountacparts.com/addtocart~year~1998~make~Pontiac~model~Grand_AM~descript~A-C_Compressor~part~60-40281.asp

Unfortunately, I do not know precisely. But for the most part auto a/c's are all the same. Below I will describe how to find it. I have also included a aguide to determine system operability that may or may not be helpful. Just trace the system with flow path described below the valve has to be between condensor and evaporator.

Reminder the flow for the a/c system is :
1. From the compressor a high pressure (HP) gas goes to the condenser in front of the radiator.
2. From the condenser a HP liquid goes to an expansion device (orifice tube or expansion valve)
3. From expansion device the low pressure gas enters the firewall to the evaporator.
4. From evaporator the low pressure liquid/gas mixture goes through the dryer2_bing.gif back to the compressor suction.

Below is a guide to troubleshoot and check system function. This can be done by most folks.

Look at the front of the ac compressor and have someone turn on the ac from inside the car. The front of the pulley(clutch) will spin when turned on.

If it does not spin, the low pressure switch (LPS) is not satisfied. Meaning there is not enough freon in the system to operate the system. Means low freon capicity because of a leak.

The LPS can be jumpered to cause the compressor to run (clutch to engaged) which will draw the freon in the system.

The LPS is usually a two wire sensor on the suction of the compressor. (between evaporator and compressor) Unplug the sensor and install a jumper, this will engage the clutch. Connect a new can of freon
and fill to system capacity.

The capacity of the ac system will be on a label under the hood, do not overfill. Probably about 2 lbs. Local parts stores (Auto Zone and Advance) will have freon with stop leak. This may help the leak. They also make a freon with a UV dye. I always add a single can with dye so that if stop leak does not work I can find the leak in the future.

The system should be filled until suction pressure is about 30 to 38 psi..

Put in a new dash control panel,new pressure switch,full of freon.fuses and relays are good. jumped low pressure switch.still no power to ac clutch. HELP..


YOUR a/c compressor is cut on by the vehicle pcm(computer).pcm sends a signal to a/c relay to energize relay which sends power to compressor. Have you checke dall the fuses with a test light? last dodge i worked on had a blown horn fuse which powered a/c system also. block said nothing about this. here is a diagram999f7d5.gif

what makes u say ur ac refrigerant has a blocked passage? check the low pressure line by touching it with ur hand while ac is running/ it has to be freezing cold/ if not cooling it means ur compressor is weak and or refrigerant is low/ high pressure line is normally hot/ check ac magnetic clutch operation must engage when ac switch is on and disengage when ac is turned off/ check ac condenser must be blocked and needs cleaning....

Ac clutch not engaging


you will have to see with test light if you have power going to the ac compressor you either have bad compressor or low pressure switch

Ac compressor will not engage when ac is on. System seems to be full of gas. Quit without warning. This is on a 2003 Nissan Altima with 2.5L. Secondary fan does come on when AC is switched on.


Check A/C compressor relay. When you say it seems to be full of gas(freon) have you actually put a pressure gauge on the system? If the pressure is too low, the compressor will not engage. If the compressor relay is functioning, check for power at the compressor clutch. If it has power to it and it still is not engaging, the A/C clutch may need replacing. It is usually almost as economical to replace the complete compressor with clutch installed than to just purchase a clutch. Keep in mind if you replace the compressor you should also replace the receiver/dryer also referred to as the accumulator.
