Chevy express conversion van air conditioning keeps breaking. this is the eighth time we have had it break in 3 years, what could be causing this? We get it fixed and within a month it stops working . The air blows out but it is not cold. The last fix was to cut the line that lead to the back of the van because that was where the leak was, so the back of the van would not have air conditioning but it still worked in the front.

I just had the same problem. If it is a regular van try under the driver seat in a plastic box. If it is a conversion van try in a pannel just behind driver seat on side of van wall behind a pannel that looks like a vent.

The rear fan fuse is located in the engine compartment on the drivers side to the bottom right of the master cylinder there is a black cover, its right in there it should be a 30 amp fuse, if you flip the fuse cover it will tell you where it is. hope it helps, but if it blown look into the fan or the switch, it blew because of a reason.

That "thing" is part of the compressor clutch. When it’s spinning the clutch is engaged, when it stops the compressor is off. If it’s constantly cycling, you probably don’t have enough freon in the system. But remember, however the gas escaped before, it will escape again, unless you fix the leak.
