In a previous post I put this, but decided it might be better to start a new one for a different issue. My 95Q is having the following issues

-Power door locks won't work on anything but drivers door,

-Power windows don't work, except drivers window and sunroof

-Clock doesn't work

-Keyless entry doesn't work

This is all I have been able to find, I have checked all the fuses and they seem to be fine, any ideas?

No ideas Huh? Me neither. To add to the list these things are also happening

-Trip odometer, AC, Radio, and for all I know everything reset everytime I take the key in and out. They work but seem to have no memory. Just weird. Since I have not heard any ideas I am taking to an electrical shop tommorrow or the next day. If they figure out what the problem is I will post it for reference. I finally seem to get this thing running awesome, and now its electrical. Ruthless!

Long shot -- check the accessory connections at the battery post. It is easy for battery acid corrosion to build up under the connectors. Clean it and give it a shot -- you may have lost the connection at the post. Just a thought on the reset issues. However, this does not explain the window/door issues.

I think it may be either the 'relay' in the drivers door or the 'computer box' in th edrivers door. The FSM has a VERY extensive self test/diagnosis procedure for this complex digital system. The system involves at least 5 different computers (boxes), a LAN, fiber optic data transmission,etc. LOTS of things CAN be the cause, but usually its a bad connection or switch somewhere. My '94 has the exact symptoms. The windows work at the individual doors, but not at the center console. Only driver door opens/locks with either the remote or door button. Seat and steering positioner work. The "failure' started 18 months ago--if keys were left in ignition--it would sometimes lock itself!. Then driver side rear door window would not/would work. The driver side rear door lock would not open -but would lock. Then one day a couple of months ago- the right side disappeared--then came back. Then..,..... its still uncooperative.

Clock is NOT part of this system BTW and its problem is elsewhere--maybe loose connection on inst cluster)
