Air Conditioning problem
1995 Chevy Blazer 6 cyl Four Wheel Drive Automatic 175k miles

Hello,
I just recently got my a/c fixed and it will do fine on bi lev a/c. But when u try normal or max a/c while driving or when engine revs the air gets sucked into the defrost or floor. My grandpa being a mechanic says it may be a vacuum hose or regulator? Haven't had time to look at it yet though. The blazer is lifted on 35s if that may have something to do with it. Maybe y'all will know what's going on because I'm not sure. Thanks

normally caused by a broken or loose vacuum connection. will have to remove instrument panel to get behind dash and check out the vacuum hoses of the HVAC system.
