Boeing 717

I started car after sitting for a month or so and have no instruments, tail lights or sunroof.
Lots of stuff comes up for 944 being some G2 relay that causes this exact scenario but I have no G2 relay.
Anyone can help??

Check the small cables and fastening hardware at the battery post lugs. Clean if necessary, and coat with dielectric grease.

Ok Paul will try that. I saw those small cables yesterday when I was looking for a ground in that area. Do you know what the smaller cables are for?

They feed everything except the starter.

Ok thanks.

I usually give the battery an overnight trickle charge after a month so all the relays see 12+ volts during cranking .disconnect the negative first.

Thanks Thomas.
It's been on a battery tender the whole time.

If the relay tests ok, try wiggling the key. Audi actually had a recall on the 91 and 92 ignition switches....but the dealer wouldn't comp my 90. Probably out of the same parts bin.

I tried the key thing.
Do you know what relay I could test?

G2 relay

My G2 relay socket is empty. That's why I'm stumped.

the second position from the front closest to the fender. swap it out with the horn relay.

Ok I'll try but there is nothing there to swap. G2 spot is empty.

The taillights fuse usually takes out the cluster lights also to make it hard for you not to notice.

Check fuse 18 which is a 7.5 amp. It is for instruments am sun roof.
