Default Courtesy lights stays on

Hey guys
Took the car for a ride tonight and the misses noticed that the interior lights remained on. I had this problem two years ago and replaced the delay timer and everything was fine until tonight. This happened after washing the car, maybe not related. It a '79 coupe, fully restored, except the wiring harness. Is there any way to bypass the delay timer, just to verify it is the problem before i order another one,
Thanks in advance
Clyde

Yes, the courtesy unit is to the right of the glove box. Disconnect that and jump the 2 white wires. I also taped off the connector so that nothing would shortout.

It's sometimes easy to forget--are you certain that the dimmer dial for the IP lights isn't turned all the way left past the detent for manual courtesy light operation.

Simply removing the delay timer won't bypass it--the courtesy lights won't work at all. As said by silvvette, you have to run a jumper between the two white wires in its connector to get normal operation.

If the timer isn't the problem remember that the courtesy lights receive constant +12V. Both the door jamb switches and the headlamp switch supply ground to the circuit.

Most potable water is a poor conductor of electricity so it's very unlikely that car washing has anything to do with the problem. Cleaning the interior and inadvertently turning the headlamp switch all the way counter-clockwise however is rather likely
