My driver’s side seat cooler and heater wont stay on. Whenever I push either button all three LEDs light up but then immediately go out. Curious if anybody has experienced this issue, or have any thoughts on what it could be?

Try to take a peek under the seat for some loose connector or chaffed wiring?

 

Thanks for the suggestion! Took a peak from front and rear and everything looks fine and snug. Maybe a fuse (that’s next on the list to check)?

 

Turn your engine on, check the voltage on the dash, push the heated seat button once and watch the voltage and check the drop. It could be that your battery doesn't have the power to do it, so it turns it off in a safety mode, sort of like the auto stop/start button. Just a thought.

 

If the car's voltage drops a lot when the engine is running and the seat heater is flipped on, the problem isn't the battery. It's the alternator. Once the car is running, the battery is really on there to be recharged. Pretty much it's sole purpose is to start the car.
