    Hello! This is my first post, I picked up a 99 suburban a few months ago. I was excited about the heated seats, but the drivers side doesn't work. Does anyone know how to go about fixing it? I got the specs from a mechanic that did the alignment, but he didn't have the time to check out the seat. Any suggestions???

    hey, welcome to the Suburban Club.

    It could be just about anything from a blown fuse to a loose wire. I would almost always start with the simple and work upwards. Check the fuses and see if there is one that's blown.

    Anyone else have experience with this?

    We've check the fuses and they are fine. I'm wondering if it might be a broken heating element in the seat itself. Anyone know where and what to check as far as voltage readings? What would be involved in replacing the heating elements in the seat?

    See if the heating elements are the same between the two front seats. if you can swap the one that works out for the one that doesn't you can see if it's the element or the connection to it.

    ^ was thinking about that, but wasn't sure how involved it is to take apart the seat. I want to make sure I plan enough time to work on this or the wifey will be mad if she's without a car because i have the seats in pieces. :shock:

    ya the old milk crate trick.
    no seriously tho my vavorite tool for testing electic sercuts is a plain old test light. check the wires under the seat for juice first if the fuses are good. then if the thing has juice going to it i wood say its screwed. if the wife minds the milk crate idea, and mine does. take the passenger seat out. and take the heat unit out of that one. two reasons for that, 1 the wife isnt sitting on milk crate, and two you get to see just how hard it is and how long it will take. or you could just swap the seats from one side to the other. if theyu are both heated and electric it shouldnt take 20 min. to do the swap. then you can work on the bad seat first. if the passenger seat isnt electric just swap the seat not the base that way she still has the adjustable seat and the heat.
    dam dude where are you that you need the heeted seat already?

    99% of those that go bad are the unit itself. The leather bottom has to be unstitched and the unit replaced. Expensive. If you get lucky, and I do mean lucky, the switch will be bad.
