Ac problem
I have a 2002 chevy blazer ls and it seams like whenever the ac is on it has a hard time running like when your going down the road it will back off instead of one steady speed. Please help!

When the AC is on it puts more of a load on the engine. When was the last time a tune up was done on it? Is the air filter dirty? There are several things that could cause the problem. Is the check engine light on?
