Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello & Welcome,
What you were checking the fuse, did you use a multimeter to see if there was power at both sides of the fuse?
OK - Thanks.
Do you have a multimeter or test light that you can do some testing with?
OK - Good.
Let me grab some schematics & we can get started.
Back soon, Greg A.
OK - Sorry for the delay - I just had to find the right schematic.
This is the main one (there may be more to come) with some key elements highlighted.
What I would do first is turn on the parking lights and check some of the other lights listed in the schematic (heater controls, ashtray lamp, etc.) to see if they light up and can be dimmed from the control. This will tell us if we are at least getting power through the dimmer control switch. If you do not see these lights on, then use your test light or meter to check the Panel Dimming fuse for power at both side of the fuse.
Please let me know what you find & we can proceed as needed.
That makes sense because the dimming of those instrument panel lights only takes place at night.
Do you have the car around now and can you do that testing? It still might be a little early in the day to see if the other lights (like the ashtray) are working.
Did you find power at both sides of the fuse?
Do the other lights dim properly?
Was that at the Panel Dimming fuse with the headlight switch turned on?
If so, that is not too good. It should be at least 12 volts.
If you can follow the schematic back, check at the Tail Lamps fuse and the Park LP fuse.
Just so you know, I will be going offline for a while, but will be back within an hour or two, at least that is the schedule.
Thanks, XXXXX XXXXX
There could be a short - or there was one. If you have the spare fuses, I would just replace the blown one and see what happens.
Sounds like a plan.
I will be offliine for a while now. Will check back later.
I'm back. Did you get into the trunk area yet?
Hi again & thanks for the accept.
Good job in tracking down the problem. Please let me know if you need more help in the future.
Take Care, Greg A.
