Driver seat heater not working even after OEM replacment

[Matahoe]

Hello and good day to you folks. Kind of diving right in here as its my first post on these forums.

I am wondering what the problem could be with my seat heaters in my 2005 Tahoe. I just replaced the drivers side with the OEM part and it went it good. It is hooked up but it wont heat up. Neither will the passenger side as well. It's just both bottom heaters. Not the lumbar upright heaters. Those work great on both seats. I looked up the wiring schematic and it looked like the bottom and upper heaters are individually connected from the module. So I am guessing this is a module problem? I guess I need to check for voltage at the connector for the module. Other than that does anyone have any other ideas or experience with this? Thanks.

Not to sound condescending but did you check the relay in the relay block under the dash on the drivers side?

I just learned today from a member that has a seat shop that I've been using my seat heater controls,wrong this whole,time. To,get the bottom and top seat heaters on @ the same time you have to use the control button on the right that looks like the bottom. For the longest time I couldn't get the bottom portion to heat and thought it was a module issue. When out and pushed the right side button and it worked fine. So make sure your using the correct button to turn them on. Sounds lame but that was my problem.
