Is there a common cause to the heater not wanting to turn off? I can't seem to get the climate control to switch over to A/C or even blow just outside air for some reason. Any ideas?

So tempting not to reply, coz' know the answer to this. Start with turning your key to the ON but not necessarily start the car. Turn your radio ON, press and hold both the radio POWER button and SCAN up button simultanously for about 5 -10 seconds look at your radio face screen change into A/C Level. Adjust your HVAC **** and watch the level scan through all the numbers from 0 - 16. If it doesn't, then your problem is that ****. DIYs are available in this forum and very helpful if you search and find them.
