The AUX fan in SOP will run for as much as minutes after the vehicle is shut off. Some people throw out FSR/FSU as the reason for every AC woe. It's like an automatic reaction.
The TOTAL charge for the system is just under 1 can from all accounts. If you need to recharged then you must have a leak. I had to replace the Service Port (High & Low) seals some years ago. The OEM seals were revised and a kit issued for older models so that standard "O -rings" can be fitted from then on. Cost was $11 per port or so then.
I took it to an AC repair shop. They found the leak and installed the new seals that I supplied, vacuumed out the system and recharged everything with the proper amount of "freon and oil for $95. Worth it when you consider the price of other parts should the recharge be done wrong!

Well to be honest I don't know if it needs to be recharged, all I know is the aux fan is not coming on, and that I have cold air on the driver side. I may indeed have proper freon pressure. If it is true that low freon levels will cause the aux fan to shut off then it is probably low, but that doesn't mean I have a leak right? Freon was never added to the car since it was bought brand new in 2005.

Did you test the AUX fan and/or the AUX fan relay to see if it either is faulty?

[hunds02]

No not yet, I am at work but thanks for the suggestions, I will test the aux fan first thing when I get home

[hunds02]

Anyone know where the aux fan relay may be?

[hunds02]

I tried to pull the plug on the pressure switch on the lower AC line, however the fan still did not kick on. Is this the pressure switch I should be checking?



I will check the voltage on the aux fan later.
