Trailblazer heated seats problem

Anyone have any success in solving problem with these?

Yes.

Time to refill the kerosene?

All kidding aside, you need to give us a little more to work with. What, exactly, is the problem? No heat at all from either seat? One seat works but the other doesn’t? Etc., etc.

What problem?

Come on! Do you really expect the OP to actually provide enough information for anyone to give an answer that has any value?

Jeez! The next thing we know, you will be expecting people to mention how many miles are on the odometer, the model year of the vehicle, the service history of the vehicle, etc.

He did tell us make of the vehicle. Isn’t that enough to work with?
