There is a module located on the firewall that has failed. They cost about $125.00.
Disconnect both heater hoses from heater core and connect them together
please tell me how to remove the heater to get too the heater coil
There is none - usually it is the module in the top of the heater / blower box (resistor module) that is the problem.
The blower motor is removed from under the hood. Against the firewall just to the left of center you will see the blower sticking out. Five 5.5mm bolts hold it on.
the blower is located in the engine compartment on the fire wall, passenger side. check the wires there for cracks or wear you may have a short there. you may have to use a volt meter and try a continuity test to ground to single out witch wire. hope it helps
Yes, if the blower isn't working. If it turns out to be the fuse, and it blows again, you probably have a bad blower motor.
Probably the heater core, it is a beast of a job to do, but is gratifying to say the least. If the is a smell of antifreeze you can almost bet it is the heater core.
If the heater fan works on all speeds, then the blower motor, blower fuse, blower relay, and blower motor resistor pack are all good. If the fan runs but nothing comes out of the vents, you have a 'mode door' issue (which might include a bad control head).
Remove the wiring harness from the back of your 2005 Chevy Cavalier heater blower motor. Remove the heater blower motor retaining bolts. Remove the heater blower fan.
It's on the firewall up high on the passenger side. You may need to remove the alternator to get it out.
Replace blower control module. Usually the fan starts acting erraticaly and eventualy just stops.
under the passenger side behind glove box the is a panel you must remove be careful for wires remove panel to display heater core remove hoses from under hod and then pull heater core out from inside passenger side
