Yes the switch can still be bad. But my bet is the relay.

Why my A/C condenser fan won t stop running, dodge ram 2008


To clarify, the compressor and fan will run in defrost mode. The compressor and fan runs to dry out the air blowing onto the windshield.
Now if the condenser fan runs in "heat" you may have a problem with the fan relay or the main controller.

1996 buick centrey fuse box


Does the compressor kick in when you turn it on?(if not it could be the a/c switch or the power to it, the a/c clutch wire connection, the clutch itself, or it's low on freon) You should hear the clutch kick in when you turn the a/c on. Low freon will also cause the clutch to not kick in. Remove the low-pressure switch plug and jump it with a piece of electrical wire. If the clutch kicks in, you just need to add some freon. Put the plug back where it was after you remove the jumper wire.
Is the belt on and adjusted to the right tension? If the belt is loose it won't cool as good as it should.
Check the freon in the system with a gage. If it's low, add some to the right amount and see if it cools. If it is overcharged, it will blow hot air, too.
The heater control valve slider should be all the way to the left so hot water isn't allowed to circulate through the heater core which would also make it blow hot air out the a/c ducts.
Good luck, they can be a pain, but with careful, step by step troubleshooting it can be fixed. There is plenty of information about a/c online to help you out. Try googling in: auto ac troubleshooting tips for more info. garcuda

A/c clutch is not kicking on in 1994 E320


How do you know the freon charge is not low ?
If the system is full, you should be able to jumper the relay and make the compressor clutch engage.
If not, the problem could be the low pressure switch or the clutch.

Compressor and fans do not turn on until rev engine


I passed this question the first time I read it, so I will take a stab at it now.
The fans don't come on until the compressor has pumped the freon pressure up to say 150 or 200 psi. And the compressor clutch has to have voltage to engage the clutch.
I wonder if the clutch is going and needs 14 volts instead of 12 to engage ? Or the relay that powers the clutch ?
Speeding up the engine would increase voltage from the alternator.
This is assuming the serpentine belt is tight and everything else is working correctly.
I think I would swap the relay with another and put a meter on that circuit to the ac clutch to see what it takes to engage it.

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.

My AC unit for a 2003 RSX-S does not blow cold air. The heater works fine and the fan is working good as well.


Check for a blown fuse or a bad relay for the compressor clutch. The clutch electrical winding may be open. When the A/C is switched on, the radiator fan should come on even if the engine is cold. If the clutch latches on and drives the compressor, then the freon charge may have leaked away from a bad compressor seal, or other hole in the system.

Dodge Ram AC not blowing cold


By pass both pressure switches one at a time with small wire or a paper clip. If comperssor kicks on replace the swich that you bypassed.
if not it could be the fan clutch ot the compressor. Compressor runs about $400.00

A/C Compressor is shot


generally speaking if the a/c clutch doesn't kick in it's because of either no voltage or low refrigerant. you can waste the money and just recharge the system and replace the a/c clutch, however it's been my expeirience that often times the compressor goes bad and that money was needlessly spent. this time of year the price to fix the system is far cheaper than the begining of the spring take the vehicle to a qualified a/c tech and your problem will cease. if you have no voltage that means the a/c clutch relay is bad. make sure all relays and fuses are good. the relays are clearly marked. quick to find out is to switch the cooling fan relay with the clutch relay if the a/c kicks in you know that relay was bad. hope this helps
