Air conditioning flow.

Hello, The air conditioning on my Blazer had been working well until recently. My problem is that the cold air stopped coming out of the front vents. The air comes out from the vent near the windshield and from the bottom near your feet, but not from the front. Is this problem from the engine side or can it be the switch or just a blockage? It's a '95 LT Blazer. Thanks.

Vent or blend door? Or Vacuum problem?
Check for full engine vacuum from engine to AC/heater controls.

The problem was that a vaccuum hose got disconnected from the back of the engine. I replaced the hose and reconnected it and all works fine again. Thanks for your reply.

You are welcome and Thanks for posting back how it went.
Glad you got it fixed and going good.
The bad vacuum will do things like that.
