Ive ran across this many times its usually the blower motor but I found that if I replace the blower and the replacement plug(thru GM)that the vehicles never had a blower issue again,so order up a motor and plug and be sure to solder the new plug dont use crimp fittings.have a good day DB

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


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.

Heat sometimes works in 2003 envoy


First I recommend checking that your coolant level is good. Please check this cold so you don't risk getting burned. I have seen too many heater complaints where the coolant level was simply too low to fill the heater core. Next, you should check if the heater control valve is operating. I don't have any GM experience, but heater valves are often the cause of intermittent heater operation in many cars. Good luck!

My 98 Buick Le Sabre heater blower works sometimes and sometimes it doesn't. You just never know.


Sounds like a bad heater control switch OR bad connector to the motor itself. I'd try your local salvage yard or EBAY for a replacement switch. Good Luck. . .

try taping on the blower motor with a mallet. if it starts when u tap it, its probably the blower motor itself. if it doesnt it is most likely the blower motor resistor. let me know which one you need to find

Blower on heater works sometimes, sometimes it doesnt. Can be driving down the road and it suddenly starts blowing. What could be the problem? A short in the wiring? Blower motor going out? Blower level...


Sounds like the blower resistor. It will either be located in the engine compartment outside the motor or inside the vehicle inside the blower motor cover. It could also as well be selector switch

Blower on the heater/AC not working on 1998 Escort, checked fuse under dash?


Ok, first off, check the fuses under the dash. If they're all good, does the blower work only on high speed? If yes, then you have a bad blower motor resistor, which is located under the hood, near the blower motor itself. If the motor doesnt work at all at any fan speed, make sure the wiring harness that plugs into the motor under the hood is clean and tightly installed. If it still doesnt operate, sometimes tapping on the blower motor housing will kick it on, but if that doesnt work, you may have to replace the blower motor. They are available aftermarket, and arent usually too expensive.
