My 1994 Buick Park Avenue

A while back I bought this 1994 Buick PA. It’s in great condition and only has 78k miles on the meter. I got it kind of cheap as it wanted to stall when it got warm and idled. I fixed that issue, and replaced the noisy water pump. It ran great for a while until last week when all the gauges (except speedometer), all the warning lights, and the entire Starship Enterprise information center lights (except the “SECURITY” light) died as I started the car.

The fuse is OK, and everything else works. I suspected the ignition switch, but that doesn’t look like the culprit on the schematics, as other things would have stopped working as well.

Any bright ideas?

Probably a fused link, or a bad relay contact.
 
Its crazy. Just this morning got a call for 2008 Nissan Altima push start. Home mechanic rip apart. dash apart. wires everywhere,,BUT power to OBD2(that usually what i need & the antenna ring on ignition to be functioning)he changed trans but now it wont read the key. Well, had to introduce new key & re set the trans parameters(which in no way should have anything to do with a key-but it throws a fault code). the home hacks think they can get a $29 china programmer & fix their cars. The cheapy programmer wiped the keys out of ECU.
Today keys made 2008 Altima, ,2000 Honda Civic & 2016 Ram 1500, 2009 Kia sedonna, 2022 Subaru forester, 2006 Ford Focus k, changed mailbox lock at a cluster & unlocked a car on my rounds today. 4 1/2 hour round trip, still enjoy going out(if its not the hood) had decent customers today

USA guitar type day..lol will just dispatch rest of the day. friday night fun fun time

That’s why I prefer the pre-OBD 2 cars:ROFLMAO:
 
What problem were you chasing and what did you find was the cause?
That’s a 2010 Camaro, the first year of the Gen 5. Also, remember GM was just emerging from bankruptcy. The 2010 was supposed to have a HUD but it, and many other planned options got cut to save GM money. Fast forward to the 2011 model and it had a HUD. A group of us bought the HUD, bezel, and switch as parts over the counter. A guy in AZ figured out a wiring harness and shared that info.

So what I was doing was installing the HUD. This was the first time I ever had to remove air bags. Felt like a bomb tech doing that.

There is a fuse panel on the passenger side behind the kick panel. I can’t tell by your picture if you are in there or not.
There are some relays and fuses under the panel behind the engine top of the firewall under the hood.

I had the duty of maintaining my MIL’s 95 Buick PA for several years.

They also have a resistor on the key and the contacts in the key slot can get corroded if it has the same anti theft sys.
clean that connection.
I would check that first.

Have you tried to disconnect the battery for a few minutes and hook it back up to reboot the computer?

These cars are comp module heavy and will have connection sensitivity probs.
Get a can of deox type electrical connections.

Maybe you can find some info on Buick forums

Good luck
 
Funny thing the older the car the simpler the fix they say.
Your car is old but not old enough and it is a great thing you found the fault.
Another 100000 miles without problems and a great drive.

Life is good,
Robin
