Controls on my seats
Controls on my seats The sides of my seats have a couple switches right beside each other. I'm guessing they are for some kind of tilt? However, they don't do anything. Bad fuse maybe?

yea same with me, I have no idea what they do, they make clicks when i press them but dont do anything, the only one that works is the one in the front to move the seat back and forth and up and down

Actually, one is lumbar support and the other is cushion bolster control (it inflates the two side bolsters on the seat to hold you in place. Tilt is controlled by the rectangular gray bar on the side of the seat - push up or down on the front or rear edge to adjust the height of the front and rear of the seat.

The power seat and rear window defogger are on the same fuse. If the fuse is OK and the seat motion switch works then check the air hoses under the seat to see if they are disconnected or leaking.

ok I took a look under the seat and everything looks fine, if the two controls are for the cusion bolster and the lumbar then there has to be some kind of air compressor, I'm guessing this went bad? because neither seat works, and when i press them i can hear clicking but no air, so I'm thinking its a bad compressor, I don't really know how they work but I can't think of another reason why there not working.

Here are GM's steps for testing "Lumbar Support Inoperative":
1. Connect a test lamp between the power seat cushion air control module connector C1 terminal A and ground. (the air control module is under the driver's seat, connector C1 is the black 6-pin connector, terminal A has an orange wire) Does the test lamp light? Yes, go to step 2. No, go to step 3.
2. Connect a test lamp between connector C1 terminal A and connector C2 terminal D at the power seat cushion air control module connector. (connector C2 is the 4-pin black connector, terminal D has the black wire) Does the test lamp light? Yes, go to step 4. No, go to step 6.
3. Repair a poor connection or an open in the battery voltage circuit of the power seat cushion air control module. Test seat operation.
4. Inspect for and repair a poor connection at the power seat cushion air control module. Did you find and repair a poor connection? Yes, test seat operation. No, go to step 5.
5. Replace the power seat cushion air control module. Test seat operation.
6. Repair a poor connection or an open in the ground circuit of the power seat cushion air control module. Test seat operation.
