Our family has two Isuzu Rodeos, a 1995 and a 1997. The AC on the 1995 works great. the 1997 stinks. On the '97 Rodeo when I'm sitting still, it gets very hot when the are is idling. My first thought is that the engine is getting so hot, I need to be moving to have the additional air cooling. However, I discovered today, the AC work fine when I'm sitting at a stop light if I just put the vehicle in neutral and give it gas. Strangely enough though, the 1995 doesn't do that. Sitting idle in the sun it cools so well that after 5-10 minutes you have turn down the AC.
Any ideas why the '97 is having this problem? Is it an AC problem, AC clutch? harmonic balancer, or just a design flaw?
many thanks for any suggestions! David
