Yea, I used the graphite and key problem solved. :biggrin: Guess the tumblers were a bit sticky, but seems stranage for a 45k mi '95.

Now back to the heat problem:

I checked the cooling level but couldn't really see it too well. Bled the cooling system for air as per manual and didn't see any coming out from any of the four bleeders. Then I added about two quarts of coolant and got the level up.

Now I can detect some heat @ 90 setting (not very much) and it only seems to be decent on upper level fan and only from the vents on the doors... center vent air is noticeably cooler

I talked to a master tech before doing all this and he said the heater hoses should be too hot to touch when the car is at operating temp, mine are not and also my temp guage registers slightly below the midpoint. Could this maybe be a thermostat stuck open? Where is the temp. guage needle normally positioned? I'm going to borrow an infared gun from my buddy and check hose temps. tomorrow.
