Ac not working.

[Fummins]

I've got a car in the shop that came in with a complaint of the ac not blowing cold. I took a quick look, the compressor doesn't even turn on. Checked the voltage at the pressure sensor, .49 volts so it's low on pressure. I poked the schrader valves and nothing came out, bone dry. First thought is the condenser took a rock but I didn't see anything out of the ordinary but I'm sure there's a hole in it somewhere. I'm not set up to recharge ac, we usually farm that work out otherwise I'd pressure the system up and be able to find the leak quicker. For now I'll be pulling the bumper and I'll post what I find. Try to pressure up the condenser with air and see if there's a leak. Hope it's that simple! Surprisingly I haven't had to change a Condenser on these cars yet. Car is a 17' with 110k kms lots of country roads.
