Message I'm having a hell of a problem with the Z. Here is the story;

All seemed well when I picked my dad up from having some maintenance done on his truck and took him to lunch. However when we went to leave the windows would not roll up or down, the Climate control would not work (and the pod was not illuminated), the power steering was not assisting at all regardless of vehicle speed, the antilock light was on and the turn signals didn't work. Everything else worked, speedo, stereo, locks and gauges etc. seemed unaffected.

When I got home I checked the service manual, but as far as I can tell there is nothing specifically common to the affected circuits that might be a culprit. Of course I checked all the fuses that had any relation to any of the systems to no avail as well as all the fusible links. (I've since checked every fuse I know of in the car and they are all good.)

After it sat for about an hour or so in the shade I went back to do some more trouble-shooting and everything was working normally.

The next day I take the car out again and everything was working fine until I parked the car for a bit. When I came back, I found the same problem as before. However this time the affected items remain non-functional and I have been unable to find the problem.

At this point I have checked and rechecked all the fuses. I have been through the relays and swapped out any that I thought could possibly have an affect on any of the items in question. Out of desparation, I have verified power at the ignition switch. And I have checked all the grounds I have been able to find. I have also inspected and reseated several of the harness connectors (M10, M11 and M12 for example) as well as the two connectors by the relay box under the hood.

I'm about to go and try to find body ground B7 but I'll be back soon in hopes someone has an idea of what the hell is going on, because I don't.

Please, Help!
