 A/C Heater Problem
I have a 1998 Ranger reg cab. The heat works fine and the a/c works but it kicks in on every setting except for the floor only one (you can hear and feel the motor kick on). Also Max a/c is the only one that actually produces air conditioned cold air. The defrost is HOT even if on coldest setting. My dome light and door ajar light stay on but I think I found out that wd40 should fix that. Any help would be greatly appreciated. |
