1988 Chevy S-10 6 cyl Four Wheel Drive Automatic 160, 00 miles
The heater/AC on my '88 S10 Chevy Blazer blows hot/cold air well. However, when I adjust the selector to any of the AC choices, the air only blows on the floor rather than
the dash vents.
I've checked to see that the 2 vacuum hoses are connected to the heater/AC diaphragm on the floor. Maybe the other ends aren't connected.
1. Could this be the reason that the baffles don't adjust to bring the air to the dash vents?
2. If so, is there a diagram showing their location on the other side of the firewall?
3. Is there a handy " how to" cheat sheet to disassemble/reassemble the heating/AC system if it turns out that the diaphragm is bad?
My Chilton manual is lacking any information on how to troubleshoot this problem,
Thanks a million,
