Either the wrong conditoning oil was used in the freon and pump is seizing up, Or the a/c clutch could be wearing out. How is the relay? It can be checked with a digital ohmmeter.

    I would check the belt tension and watch while engine runs to see if a/c clutch engages. I am guessing the clutch is bad.

Subaru tribeca air conditioner not working


Check the power going to the compressor clutch with the AC switch on.If there is votage across the clutch, it may be bad. Not engaging.
If no voltage, you have test the circuit to see why no volts are there.

The AC in my 2003 VW Convertible is not chilling enough. What can I do about it?


Your system may just be low on freon. Most auto parts stores sell 134a freon for about $10 a can. If you visit an Autozone store the parts counter personnel might also show you how to add freon to the VW Beetle, it's not hard once you know where the correct port is located. You simply start your car, connect the freon dispensing hose to the AC port (there are two (2) ports, but the hose connection will only fit onto the smaller of the two (2) ports - the low pressure side). Allow the car to run while the can is discharged into the AC system, generally takes 10-15 minutes. Most dispeners have a freon pressure gauge on the hose portion that attaches to the can. Never disconnect a partially empty can unless there is a shutoff valve, and the valve is closed all the way. Better to add the entire can to the AC system.
If you have never added freon to your 2003 VW Beetle, that's the most likely problem. You could also have developed a slow leak in the compressor or AC lines, so I recommend adding freon WITH a sealant in the same can just in case.

The job would cost between $45 and $65 if you take it to a reputible mechanic to perform. That usually includes a full blown pressure test of the AC system. and a whole list of costly recommendations.

Ac not workng


The musty odor is moisture in the HVAC box. Someone needs to check and see if the system is full of freon, then check the circuit going to the ac clutch for power.

2002 ford mustang air conditioner stopped working. How do I locate the problem?


FIRST I CHECK ALL FUSES AND RELAY.TO BLOWER MOTOR IF IT STOP BLOWING.AND CHECK FUSE TO HVAC SWITCH CONTROL.AND CHECK FUSE / RELAY TO AC COMPRESSOR.IF FUSE / RELAY GOOD POWER GETTING TO AC COMPRESOR CLUTCH COIL AND LOW PRESSURE SIDE 28 PSI AND HIGH SIDE 200 PSI. CLUTCH COIL IS OPEN.IF REFRIGERANT LEVEL LOW YOU MAY NEED MORE REFRIGERANT.YOU NEED AT LEAST 28 PSI ON LOW SIDE AND 200 - 220 PSI ON HIGH SIDE.IF ALL IS GOOD STILL NO AC PROBLEM COULD BE A FAULTY AC CLUTCH CYCLING PRESSURE SWITCH.

1986 chevy S10 has no power (12v) at fuse box on the fuse for ac clutch. checked both sides of fuse to ground 00v. ac/heater fuse 12v both sides (fan) works fine


hello, check all fuses, and relays, make sure wires to ac is not broke or has been pinched, sometimes you can run hot wire from battery, to compressor, touch hot side of plug in on comp wire see if it will kick on, if so sounds like a short, if compressor dont kick on with hot wire run to it, tap the out side of comp clutch and see if it kicks on, these compressors will not kick on any way if they are low on freon, once freon is full it should work.

Ac/Heat stopped working, Transmission has "reduced funtion" can the 2 be related, and how to fix both or either? Also driver side door handle became inoperable, dealer "fixed" ,


Most likely in a word NO - the two are usually kept away from each other as they both require a lot of amperage.

Look in your manual for where the fuse is to the AC / Heat unit. On some cars there are two. I would simply replace the fuses because if they are burnt they may be bad in an area you can not see. If you test them - hold a fuse up to the light - and look very closely for discoloration or a gap or both.
With the newer fuses it is just easier to replace as sometimes on rare occasions a good fuse being loose inside will not work either and these are hard to spot -
if you replace all fuses and still nothing - check your freon level - newer units like you have will shut off automatically if low on freon.
also call the dealer with VIN number in hand for a check on recalls with the trans issue.
