Driver's seat gone dead - wife can't reach pedals!
Advice please. My wife got into our 87 S4 auto and couldn't adjust the seats as all the buttons were dead. Both motors (I presume there are two) have been trouble free. No noise. no clicks, nothing. Have checked and replaced the fuse twice - no joy. Have tried looking under the seat to check for loose wires but difficult to see what is going on without manually winding the seat forward with the special tool - and then I'm not sure what to look for. Any suggestions.
Thanks chaps.
Mark

Sooooo, let me get this straight......your wife is unable to drive your shark.....and that is bad because.........
Sorry I couldn't resist. Seriously, I have found that if the seat is run all the way back to the stops, sometimes you need to hit the switch a few times to get the seat to move forward. I suspect the gears may bind at the end of the range and it just needs a little prodding. If that is not the issue, I am sorry. I have experienced no other symptoms with my seats.

The problem is that, despite being nearly a foot shorter than me, it won't stop her driving it - and she's dangerous enough without not being able to reach the brake!

My guess is that either switch or a connector/fuse has gone south. Pretty rare for the motors to go bad. Mine have always worked, or at least they did 2 years ago (my wife doesn't drive it). I'd get a multimeter out and start tracking it down. May be easier to pull the seat first. 4 allen-head bolts.

Andrew, sounds easier than fiddling around under the seat. Do the motors etc just lift out with the seat once the allen bolts have been undone?
Thanks

I suppose I could always get a taller wife!

Mark,
It would be very weird to have all seat switch functions fail simultaneously... being that you've checked the fuse, I'd look next to the relay that drives the motor. This link should be helpful:

Having a mistress a foot taller would solve one problem ... but may create 10 more ... Nah, fix the seat!
As Gretch noted, the seat being stuck in gear can be a problem; however, the motor will still energize audibly. If it does that, push on the seat back while contacting the forward button. This has worked ....
If the fuse is good and shows 12v, then pull the relay - IIRC, this one is under the seat front. I know, the diagram doesn't mention one, but as I mentioned "IIRC" - it may only be a bad memory. Anyway, probe until 12 v is found at the switch or plug feeding the motor: there is one motor controlling fore/aft which sits under the cover front and center of the seat. There was a thread posted yesterday on a similar issue.

OK there is a single motor in the front which moves the entire seat forward and backward it has the emergency drive plastic gears and two flexible drive cables which turn horizontal shafts on each side of the seat base. These threaded shafts turn inside a nut ,if the seat is run back too far (pushing back with your feet) you can run out of threads and jamb the rods into the nuts. Two other motors raise and lower the front and back of the lower seat. A fourth motor in the headrest reclines the seat back. So odds are that all 4 motors did not die at once nor is it likely that all the switches failed at the same time. If you are "blessed" with memory seats (three litlte buttons on the door)it all gets to be MUCH more complicated.

Solution: Trade in for taller wife.
I went from a 4'-10" first wife (now about 300 lbs) to a 5'-2" second wife. y upgrading to my 5'-8" current wife, we no longer have these problems.

At this rate, in a few more years you will have to remove the back seat of the 928 to fit in the 7'+ wife.....

Yeah, and let's hope the later ones don't gain weight at the same rate as the first one did or you are gonna need a flatbed............
