Hi Folks, I just bought a '91 Q45 and find it has the following electical issues:

1) Driver power seat inoperative.

2) Sun roof inoperative.

3) Interior lights inoperative.

4) Radio inoperative

I went through all the fuses (left dash) --- they seem to be fine (maybe I should double check with an ohm meter --- but none seemed blown). Are there other fuses of circuit breakers? Do these four issues have any common circuits?

Since I am a total novice to this, can you suggest a diagnostic approach?

I bought this car for my wife and the seat - is all the way back and she can't drive it.

Any suggestions are apprecaited!

Thanks,

Dave

Get a FSM and all the TSB, a DVM, and start tracing.

Have you done the timing chain guides? If not, don't drive it.

Go to NICO and start reading.

Hi, Thanks ---

well. by dumb luck I fixed the driver powere seat simply by 'jiggle' of the wires under the seat (Hmmmm???).

any thought on where the Radio Fuse might be located?
