I have a 2011 Tahoe with heat and cooled leather seats they use a thermoelectric unit in both the seat back and seat bottom my driver's side works great but the passenger side comes on and runs briefly and shuts off even though the indicator lights on door are still lit up. I was told by a friend of a friend to replace the back blower unit at the cost of about $150 and it did not help. Has anyone ran across this issue?
