Airconditioner does not blow cold

Defective compressor clutch, or ground fault in the ac switch circuit.
Disconnect lead to compressor from ac switch.
Run a fused line from the battery to the compressor, if it works without blowing the fuse, check for fault in the AC switch circuit.

ok if it is a reverce cycle airconditioner theres either a problem with reversing valve, gas has leaked out, compressor is blown or a possibe pc board depending on make/model/age of the unit.

if it is a gas heater it could be a possibility its the solenoid valve that controls the gas flow,


NEED MORE INFO

i think you are low on freon. your compressor clutch wont engage when you are low lift your hood and turn air off watch the compressor and have someone turn on the air and see if clutch engages on the compressor good luck

After looking at the wiring diagram, it looks as if you have a A/C relay that is powered by the 30 amp fuse, try disconnecting the A/C compressor's wiring harness at the compressor after the fuse is replaced, then crank the engine and turn the a/c again, if the fuse does'nt blow this time, your A/C compressor may be drawing to many Amps.

when you turn on the a/c does the compressor start turning?...find the compressor, and you will see its pulley turning all the time..but when it kicks in, you will see the inner part turn as well, you should hear it click when it goes on.
if it doesnt turn, could be low on refrigerant, or maybe your fuse is bown?

hope this helps

HI!!

When your vehicle overheats, the computer shuts off the A/C compressor to protect the engine by reducing the extra load.

Have the cooling system serviced, once fixed, the A/C should work fine.

Don't forget to rate this post. Good Luck!!!

If there is no refrigerant in the system you have a leak.
I suggest taking the vehicle to a shop who employes HVAC technicians or equilavents. Dealing with refrigerants is dangerous and illegal if your not certified to do such.

Reasons for lack of cold a/c is low refrigerant. Does compressor engage and spin when a/c turned on??

Reasons for cold air from heater are

Blocked heater cores
Faulty thermostat
Faulty heater controls
Faulty heater tap.

check for system leacks (lines,fittingis,comperssor,dryer,condensor )

You need a new airconditioner compressor. The baring have failed.
