So I get in my car this morning and turn on the defroster because there is some condensation on my windshield. Well, the minute I turn it on, my idle jumps up, so the BAC is working, and then my CEL comes on. WTF? So I turned the defroster off, and the CEL went off. Turned it back on, CEL comes on. What related to the Heat/AC controls could cause the CEL to come on?

Did you pull the code yet?

Searching for a piece of wire now, I just moved into a new apartment so all my car stuff is packed away somewhere.

Icemark

air condition out of freon???

Just guessing, but pulling the code will tell for sure

Here are the codes I pulled, some I know the reasons for.

1 - Trailing coil: Bad starter cranking the car too slow and sometimes it would fire but the ECU thought other wise and cut the trailing coil

2 - CAS: Same as above Im assuming

5 - Knock sensor: No clue, where is it located, and what could be the problem

13 - Pressure sensor: How can I test it.


How do any of these relate to my AC/Heat?

Well, I just reset the ECU then started my car up. Turned on the heat again and the CEL came on. So I turned it off and checked the codes again, all that was there was a number 13 for the pressure sensor. Weird.
