WARNING: This page is about a different car, the 2000 Chevrolet Corvette and 1999 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
Following conditions may cause an intermittent malfunction:
- Intermittent short to ground in right window down switch input circuit (Tan wire).
- Right window down switch circuit is shorted to ground internally or is sticking.
- Right window down switch was depressed for longer than 20 seconds.
If Tan wire is shorted to ground or right window down switch is stuck closed, left window will remain down at all times. Using scan tool, select Right Door Control Module (RDCM) inputs and monitor right window down switch status. If scan tool displays ACTIVE, disconnect right window switch. If status did not change, check Tan wire for short to ground.
