A/C Question

A/C Question
I swapped out my stock pullies (U/D, water pump, alternator)with MotoBlue ones a couple months ago. My A/C stoppedblowing cold airas soon as I installed them. I lived withdriving with the windowsdown for 2 months, but need my A/C back asapbecause I'm selling the car. I heard the aftermarket water pump pulley is what knocks out the A/C, so I changed it 20 mins ago and put in a new belt (1 inch shorter than stock) to compensate. Test drove it, A/C still isn't blowing cold air. WHAT THE FUKK. Can someone help me?!

I've had UDP's on the last two cars I've owned and they didn't effect the A/C at all.I'd start by checking the fuse and if that's OK I'd look for a disconnected wire or a low charge.

Did you check when you put it on max air that the
compressor was actually engaged and turning?

+1, make sure the low pressure switch does not have the compressor disabled. Might be a simple as 9.00 can of freon.

Alright well on the way out there I realized that if the pulley wasn't turning, my belt would've been fried by now. I checked it out anyway and it's turning just fine. But what's this low pressure switch and where is it located? I didn't know there was such a thing.

Looking at the pulley turning is not enough.
The pully ALWAYS turns. It is the shaft on the
compressor that turns the compressor piston.
The low pressure switch cuts off the compressor
magnets when the volume of freon is too low.
Sounds like that is the problem. You probably need
to add one can of freon.
You need one can/with oil, a kit to add it.
You will have to short out the low pressure switch
to get the pump to engage and suck in the freon.
The freon goes in a warm bucket of water to keep it
from freezing.
