I have a o4 express conversion high top. I noticed my temps were up in traffic today. The a/c started blowing warm air. I can hear the clutch fan as the traffic let up. The a/c started to blow cold air again. I'm wondering if I should change the clutch fan or the water pump. Maybe both need to be eplaced. Has anyone gone through this? Thanks for your assistance

 

I'd have someone look at the refrigerant. At 14, it wouldn't surprise me if it were low. The fact that the clutch is activating and it gets cool again tells me the clutch is fine. And if you're in any heat advisory areas, again, no surprise there.

 

Same.....warm air at idle, but getting cold at higher rpm is sign of low refrigerant....

 

Thanks guys. I'm gonna get me a couple cans of refrigerant . Again thanks for your help.

 

Use a gauge, don't over fill. I'm surprised you hadn't needed to do this sooner.

 

You need to make sure there is enough oil in the system too, or the seals will dry out and you will keep losing refrigerant. I would get it evacuated and filled at a shop. Low oil will fry the compressor....

 

Clutch fan is probably bad as I had to replace mine a few thousand ago.
