Question about 2004 GMC Envoy

1 Answer

2004 gmc envoy heater intermites when using... only turns on once in a while on all settings, but seems to only work when it feels like it

Sometimes heater will go days without working, then all of a sudden it kicks in and works on all settings.. Usually doesnt work, but sometimes will kick on for a few minutes to a few hours.. its non predictible, wondering if this may be a relay issue?

I am kinda having the same problem not as bad as yours. They replaced my relay or what ever it is 2 times. When it got down to 9 degrees mine quit working again for 2 days. It started working again but took it back to dealer anyway. They had a new part they put in then they called us and told us the blower motor is burnt up and it is gonna cost us $300. We asked how it can be burnt up when it was working when we brought it in. They said I don't know but said it is. After talking to 3 people and no solution to this, we told them to put the old relay in cause we're not paying 300 for something that was working. So far still working but sure it will quit again. Will never buy another GMC produce.

2004 GMC Envoy- Whenever the heater is turned on the RPM drops to about 500RPM and sometimes dies. What could be causing this problem?


The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean.

When turn signals are used, they stop blinking after 2-3 blinks. All lights are good.


Find your Flasher relay usually under dash divers side of sometimes under hood drivers side. Sounds like once it heats up it stops working...
