Question -
i have a 92 cadillac deville 4.9, my a/c is not moving air through the center dash vents where would they need to be hooked up if not properly wired (behind the radio, under the hood?) and how do i search for error codes to come up in my information center?

Answer -
You stated: where would they need to be hooked up if not properly wired.


This is quite an unusual statement. Has someone been in the dash to replace the radio or something ?.

1. Ignition ON. Engine OFF.

2. Simultaneously push and hold the OFF and WARMER buttons for 3 seconds and release them.

3. LETTER/NUMBER codes will appear and then stop.

4. Tell me EXACTLY what appears on the screen in the EXACT order in which they display.

5. turn off ignition.  

Answer
There are no pictures of the fuel lines.

If the air is mostly going to the defrosters this is caused by a vacuum leak between the engine vacuum supply line that goes thru the firewall to the A/C programmer under the dash.
