Question about 2004 GMC Envoy
My oil gauge doesn't work, speedometer stays at ten, and my window/heated seat controls stopped working. all these symptoms showed up at the exact same time. i figure they are related.
Did you check your fuses?
If ok then disconnect the battery for a couple min and reconnect this might fix the problem.

Try this remove the ckt breaker for the power seats the ckt breaker is located in the fuse box inside down by the drivers left foot. leave breaker out for about 10 seconds then reinstall it and see if the seat starts moving. If it does there is a reprogram for this and needs to be done by a dealer or someone who has access to be able to reprogram your vech.
several things could cause your heated seats to not work. If the seat and heated seat seat stopped at the same time could be the reprogram could fix it. If the heated seat quit working at a differant time it could be the seat heater element. get a schematic of the heated seat and ohm the wires for the element. If either element tests open then the element will need to be replaced. You might as well replace both of them at the same time since the seat covers have to come off to replace the seat heaters.(back and bottom ) If one element is bad then both heaters quit working.
