First of all I want to tell you how happy I am to have found this site. It has saved me $ and Hrs spent under the hood. My problem is this (2 actually) when ever I turn a corner I hear a sloshing sound coming from behind the middle console. Is that the heater core doing that? And the air for the heat/ac only blows out of defrost. I can turn that switch anywhere and it still blows out the defrost. Thanks for any help you can give.....

 

Sounds like you have lost the vacuum supply from the engine to the HVAC system.

And the sloshing can be a heater core issue.

Both of these problems are fairly well documented in other threads. To move any further with this thread, you have to let us in on one secret... What are you driving?

 

I am driving a '97 blazer sorry i didn't put that in.
