Hi all,
I have a 85 C-10, but with a '88 TBI engine. My problem is in the tempature control though. When the heat is on it blows a few degrees warmer than the outside temp, with the A/C, same thing, a few degrees below the outside temp. I have put in a new Coolant temp sensor, new Rad (because of leak). The A/C is charged properly, and the heater core isn't blocked. I removed the glovebox and watched the cable for the temp select move back and forth, apparently with full range. Possibily the blend door isn't sealed properly, alowing outside air to pass? Any help would be appreciated.
