Rebuilt truck a/c not cooling as it should. by Robert
Post New Message We recently bought an '85 Winnebago Elandan 32' Class A. It's built on a Chevy P30 chasis with a 454 engine. The a/c hoses were disconnected when we bought it. They were all corroded inside. We took it to the local Goodyear a/c service center, and they converted it over to a R134 system. Everything (hoses, compressor, accumulator-drier, expansion valve, and even added an electric fan to further help cool the condensor) was replaced except the condensor which was still good. They flushed the entire system and checked all air ducts and routing.

The problem is that the air coming out of the vents is still not as cold as it should be. Running at Max with the fan on high, it feels more like having it on low when compared to my '94 Suburban; the air is cool but not cold. This is OK as long as I stay at the coast, but going inland at 100+ degrees, this can get uncomfortable.

According to the Goodyear guys, the system is functioning as it should. The lines (?) in the air box (?) is freezing/icing up, but the air coming from the vents is only 45-50 degrees. They said they have tried everything, but it might just be a flaw in the blower's design. They said that the way the blower is set up, it's pulling the cold air through (thereby warming it as it passes through the blower fan), rather than pushing it. I feel that they are sincere and honest with their work, but this does not solve the problem with the a/c. Is there anything else that can be done? Or, is this common with older Winnebagos? Any advice or suggestions will be appreciated.
