Try replacing the low pressure switch on the accumlater and see if it works, does the fan work at all? if not then the module for the fan is defective and you will have to test the fan switch or the resister pack for the fan thats mounted on the heater box and is mounted by two bolts 1/4 inch diameter. the resister pack is 10 bucks. and only takes 5 minutes to replace.

Air conditioning problem


Air Conditioning problem
2004 Chevrolet Impala



Ac is not blowing out cold air. You have to put gages on the system and it shows its has freon.Checked all fuses and relays. The two fans in engingine compartment do not come on when the ac is turned on but does when the engine gets hot. The compressor engages when turned on also.
If the magnetic clutch engages the compressor and still no cold air could be still low in freon or the HVAC unit.

Blower motor not working all the time...if I bang the dash near the glove box, it comes on then works great. Is this the switch assembly, the resistor problem, or should I be replacing the blower motor?

My 2005 ford ranger a/c is not working all the sudden, could it be a fuse?


My AC quit all of a sudden and it was a switch in the ac line. It was located on one of the air conditioner lines almost next to the firewall. Looked like a little box. When the p/u was running and the ac was turned on, I tapped it with a screwdriver handle and the ac compressor came on. I think it was a low pressure switch and is supposed to keep the ac from running without any freon, so you might try that. Best of luck.<!-- from fixya rte -->

Air Cond. not working. Clutch does not engage


On the low port side (the side you put freon in) there is a low pressure cut out switch, pull it off and run a jumper wire across the two connectors, if the compressor kicks on the you are low on freon. and have a leak some where.

We have a dodge caravan, and blower motor quit working so i replaced it, it still doesnt work, is the only fuse panel under the hood


tn my 2005 Grand Caravan there is a resister unit located behind the glove box that also has a "thermal fuse link". This fuse is not replacable and if it blows your fan motor will not work. The replacment unit is $14.00 at Auto Zone.

It could be a bad blower motor - tap on the blower motor with the end of a hammer when you have the switch in the on position - if it comes on then it is a bad blower motor. If it doesn't come on I would check to make sure you are getting power and ground to the HVAC control head.
