My heater controls have developed a mind of their own. Some times I get hot air and sometimes I get cold air but usually not when I want either. I took it to an out of town dealer ship and their mech diddled around with it for about 45minutes and told me that he didn't do anything but it started working properly and he had "cycled" it at least a dozen times and it worked fine every time.( it was nice of him to charge me nothing too) It was OK for about a week and a half and now it heats(a little) with the selector on AC but gets ambient air temp when the selector is switched back to the vents(floor or def and in between) with the temp selector on full hot.
Whats the problem and how much does it cost to have it fixed at the dealer.
