Hey All! I have a 1998 Jeep grand Cherokee limited 5.2L automatic with 100,000 miles on it.

The drivers seat controls are not working at all. None of them. The passenger controls work just fine...

So far I have checked....

All fuses, non are blown

Relays, the passenger seat works just fine so that leads me to believe it is not a relay issue

I have 12v power at the plug that goes to the seat

I took the control switch panel off the drivers side and brought it to the passenger side to see if it was a bad switch but it moved the passenger side just fine so that leads me to believe its not a switch problem...

I have 12v power coming into the control switch harness

I hot wired one of the motors and it moved....

I removed the memory seat module which is under the driver seat

and I can see one of the diodes is possibly fried.....so my question is...could a bad memory seat module cause the whole seat not to work...?

I have been chasing my tail for the last day trying to trouble shoot it..Any other things I could trouble shoot to trace down the issue?!

Thanks in advance Steve D

I am curious however as I've not heard of a memory module for the XJ's, do those seats let you pick from pre-set positions or something like that?

 

Awesome thank you, I will do that now
