94 Camry 5sfe no heat - Toyota Nation Forum : Toyota Car and Truck Forums

The other morning it was a little chilly so I went to put the heat on in my car. Air was coming out cold. I checked a bunch of stuff and couldn't find the problem. Last night I looked again and found the valve on one of the heater hoses that goes into the firewall. The valve looked like it was turning as I moved the knob on the dash. But looking closer I saw that there was a little screw on top of the valve that was loose. I gave it about a 1/2 turn to tighten it. Tried the heat this morning as it was kind cold out and it works fine now. So I guess the valve was not opening and by tightening the screw it works now. Just thought I'd post this in case somebody has the same problem.
