DAYLIGHT RUNNING LIGHTS STAYING ON.

Just started a new problem (as if I needed more with the 94 Buick MAF sensor).

After driving the lights will sometimes stay on, and stay on for a long time. The switch doesn't have to be turned to turn the lights on their automatic, and fooling with the switch does nothing.

I can even sometimes take the negative battery cable off, and put it on in 5 minutes and the lights come back on. Had to leave it off all night, in order to get the lights to stay off, without discharging the battery to nothing.

Sometimes the inside lights stay on as well, but not verified. (I wasn't there). There is no switch/scroll wheel on this car, to change the duration of the lights staying on/coming on at night, like my Mercury Sable.

Do you
have the same problem?

The lighting timer relay is malfunctioning. It's in the Relay Center box in position #1.

Oh no, not that one. That's a $164 part. I looked it up last night at Advance Auto. I'm gonna be in the poor house with these cars. Unless I looked up the wrong part.

Try a junkyard, especially a pick and pull. Probably less than $5. Plus admission fee. Just check the wiring to the relay center before you choose one. Write down the #s on the one in your car and take that with you so you make sure you get the right one. I don't have a reference that lists what models and years have compatible relays.

Bravestar1,

It never rains but it pours.

Before you jump into it, have you checked the autolamp relay? If it sticks, it means the autolamp switch has been bypassed. Check the DRL relay as well.

Mike, I don't see any timer relay in the circuit. It seems the GEM is the one controlling it, underdash.

That shouldn't be too expensive. Only the GEM is the expensive one.
