GMC Repair: 2002 GMC Yukon Seat Heater, gmc yukon xl, gmc yukon xl denali

Question
Hello,  I have a 2002 GMC Yukon XL Denali w/ 6.0.  The drivers seat quit working about a year ago.  The other three seats heat just fine.  With all the cold weather, my wife is really complaining.  Any suggestions.  Thanks

Answer
Hi
First quick checks
SEO fuse under hood fuse block
IGN 3 fuse, drivers side fuse block
if either blown, replace and recheck
Does the switch light up?
The three main  items that COULD go faulty would be
the switch
the heated seat module
the seat bak or cushion heater element.
I would HIGHLY recommend taking it and having it professionally diagnosed, so needless money will not be spent on replacing good parts.
If you have good automotive electrical experience, I'll GLADLY send along the diagnostics for you to preform.
If needed, just follow post back, and click the private box.
I hope this helps
Good Luck
