The most common cause of your lack of cooling is no or low refrigerant charge in the system, in most cases this is due to the front shaft seal of the AC compressor on the engine leaking, if it is leaking you will see oil deposited around the front of the compressor behind the drive pulley magnetic clutch. Of course there are other places that leak and other problems that cause lack of cooling, but check for a lost charge due to leakage first.

SOURCE: ac compressor cuts on and off and no cool air blows out .

Too many reasons why but it probably needs to go in for repair. compressors will cycle on and off if the system is under or over filled. If there is a flow restriction, a collapsed high pressure hose, clog somewhere in the system(some vehicle owners put sealant or refrigerant with sealant in it) bad idea. Good luck.

SOURCE: radiator cooling fan 30 amp. fuse keep blowing

The fan may run with jumper wires but if it''s blowing the 30 Amp Maxifuse it's needs a new or used fan motor.It's pulling too many amps.I have almost never seen a fan relay concern.Only other thing you may check is the wiring down near the fan shoud I have seen the 2 wires get loose from the conduit & melt onto exhaust manifold.Hope tHis Helps

SOURCE: 1992 5.0 camaro no cooling fan except with ac

Yes there is a relay, but first answer this question, do you know the fans don't come on until the engine temp is above 230+ degrees F.? That is almost in the hot zone. run a scanner on the engine and watch the ECT sensor temp reading to verify proper cooling fan operation, a quick test to see if the system works is to unplug the ECT sensor, the fans will go into failure mode and turn on to avoid damage to the engine.

Cooling fan temp light stays on when air condition is on. fans are not kicking on. Is it the fan module ?


I didn't know it had a light on the dash that said "cooling fan temp".
My 93 doesn't.
The cooling fans are controlled by the computer and turned on when the ac is running or when the engine reaches 220 degrees.
A mechanic would check the fuse and relay for power and the fan motor for power and ground.

AC and Cooling Fans Not Working


Try installing a jumper across the N/O terminal at the relay socket. Temp sensor in the radiator or in the thermostat housing supplies the signal for the relay the other relay signal is supplied by A/C in on position. both fans will run continuous with A/C on. One fan runs intermittent relative to water temp. Be careful not to blow a head gasket. If you leave the jumpers in place, the fans will stop when the ignition is turned off, save the engine until you isolate the relay signal problem. then simply remove jumpers and reinstall the relays

Ck engine light problem on 2001 Impala


Well the code is for the circuit - the computer commands the relay to turn the fan on and it doesn't happen.
The computer provides the ground for the relay.
If you have replaced the relay and the fan and the fuse still blows, I would look for a problem in the harness between the fuse box and the fan, including the ground circuit for the fan.
The fuse for the cooling fan is usually a 30amp marked "cooling fan" in the fuse box in the engine compartment.
Do you know what the 25amp fuse that is blowing is for ?

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.

My ac is cold and is basically fine. but the problem is that it doesnt blow hard. it sounds like it is but you barley feel anything. what do i need to replace so it blows hard?


For this issue, have the evaporator cooling unit cleaned. The reason why it doesn't blow hard is the dust and dirt are covering the evaporator cooling unit. The dirt and dust are also very harmful to the cooling unit. Have it cleaned and you will see the difference. Hope this helps.

The ac blows but it dosent blow kool fan works and its full of freon what should i do and if it blows kool it only blows kool at night


You have the system leak tested

Then have it evacuated & leaks repaired
& recharged

It only cools at night because it is low on refrigerant
& during the day it is so hot in the condensor
that it boils off refrigerant before the expansion valve
& doesn't cool the evaporator

No -- you can not add & polute the atmoshpere

I would think there may be air in there also

Can not work on it yourself

Cooling fan fault and AC fault


Cooling fan Fault - your big fan at the radiator is bad (open hood & see if its running- if not turn off car immediately) & that trips A/C warning. You need a mechanic as a computer chip controls that.
