Hello Everyone!

I'm in desperate need for help with my '95 S10 Blazer, its very hot in Vegas and I'm going crazy!!

The problem it's that the a/c does not blow air through the front vents on either MAX or NORMAL setting, it blows from the bottom and upper front vents ( windshield defroster vents) only. Now, the only way to get air through the front vents it's by setting the system to BI-LEV but it blows through the front only for a few seconds then switches to the bottom and upper front vents, the only way to get it back to work its by pushing the brake pedal and obviously it's very anoying driving under 105 degrees average hitting my brakes every 20 seconds to get fresh air through the front vents.

Any help will be greatelly appreciated!

Thanks.

 

You need to look for a vacume leak somewhere. Raise the hood and on the driver's side their should be a black ball. First make sure it's their. Next their should be a vacume hose plugged into the back of it. Check that hose to make sure it's not cracked or leaking.

I like to find vacume leaks with a spray bottle filled with water. I just spray down the vacume lines and listen for a change in the motor RPM.
