Buick Park Avenue headlights wont turn off

Buick Park Avenue headlights wont turn off

Shops are reporting a Buick Park Avenue headlights wont turn off problem with the GM “twilight sentinel” system on Buick Park Avenue vehicles. Owners report that the headlights will not turn off.

Start your diagnostics by unplugging the head lamp switch connector from the switch. If the headlights now go out, replace the head lamp switch.

Get a new headlight switch from Amazon.com. Standard Motor Parts #DS717 fits Buick Park Ave & Park Ave Ultra from 1997-2005

If the lights do not go out, check the white wire at the lamp driver module (located under the center of the instrument panel) for a short to ground pin J and pin B1. If the white wire is not shorted, the problem is in the lamp control module. Replace it.
