Hi welcome to the forum.

Have you tried a Haynes manual?

Hi and welcome to the forum. You won't find this latch as a separate item. I guarantee that GM sold it as a complete console assembly, and I would be very surprised if you could still find it stocked anywhere. Search the usual online GM part suppliers or ask your local dealer. I recommend you look i...

You probably need to replace the key cylinder and ignition switch. But I don't understand how the Passlock immobilizer doesn't kick in unless you've defeated it somehow.

Here we go. Should be #7
007 Sensor, oil pressure indicator gage (60 psi)(1987-89)(acdelco #19244932)

Welcome to the forum. One is a pressure sensor for your gauge. The other is a fail safe switch that cuts off the fuel pump to save your engine from failure if the oil gets too low (and maybe turn on a light in your cluster). Below is a flow chart for diagnosing gauge issues. I believe the J-24538-A ...

bolts with 10mm heads are usually M6. You can always just ask your dealer to order you some. They have a catalog.

Nice work. P0430 does not affect engine function at all. It's purely an emissions code. Driving for too long with a misfiring engine will kill a catalytic converter from all the fuel being dumped into it. When the engine light is flashing, it's saying "you need to stop driving and fix this righ...

glad you found your issue. Rockauto has good parts, and less good parts, depending on how much you want to spend, and they grade them for you with categories (economy, premium, etc.). They even sell genuine OEM parts. Of course this all goes out the window when you have a vehicle that hasn't been in...

Welcome to the forum, Wheeliedart.
Glad to have ya.

Hi welcome to the forum.
Check for bad grounds and corrosion in the sockets. If you measured power then switches are fine.
I don't know what left/right pins are but black wire is ground. Yellow is low beams, and dark green+white is high beams.

Since the G80 unit is purely mechanical, I believe control module programming will be identical. Wheel speed sensors will compensate for any limited slip activity. You can try asking , but I think the dealer will refuse. They only use new OEM parts based on your VIN. The part is "cheap", b...

it's 100 % logical and not absurd at all.
As I said, disable it at your peril. A couple of ounces of fuel is not worth replacing the AC system. As an engineer you should also understand that refrigerant lubricates the system.
