A/c stuck on

Asked by Oct 03, 2015 at 07:03 PM about the 2003 Ford Explorer Sport

Question type: Maintenance & Repair

I'm getting no heat just cold air. Took to local shot and was told that for some
reason the a/c is staying on. But on one can tell me why. Need to know if it's
something I can fix or a dealer will have to. Open for suggestions.

Sounds like the HVAC control computer is messed up, you can try removing the heat and cooling fuses for a few minutes, that will reset the HVAC system and see if that fixes the problem. A temporary way to shut off the A/C is just unplug the cycling switch the is on the accumulator tank or unplug the compressor itself, the only draw back to this is when the humidity gets too high the windows will tend to fog up, then you will have to switch to defog and open a window slightly to let the humidity out.
