Could be,
a bad blower motor,
a blown fuse,
a bad resistor,
a bad switch,
damaged wiring,
Well I found if I do not take it for granted and buy it a present once in a while and possibly sing to it it will turn on after a while
That happened to my catera too and it was just two blown fuses so get a fuse tester and test the fuses or take it to a shop and have them fix it for about $80
Raise the hood find the heater motor tap it with a hammer. It should run.
you have a bad heater core
that has a lot to do with.if your heater core is pluged up you wont get any heat out of it.
I have a 1978 coupdiville cadillac my blower quit working and there is a relay above your fuse box and if it goes bad your heater wont turn on. I had to replace it with a after market heavy duty relay away from where it is originally plugged in. Also my ground wire connection was dirty and wouldn't turn on until I cleaned the connection so try that and see if it works or you might need to replace the motor.Fleetwood_brougham_BLOWER_wont_turn_onDiscuss:Fleetwood_brougham_BLOWER_wont_turn_onFleetwood_brougham_BLOWER_wont_turn_onbrougham BLOWER wont turn on?&content=&lng=en&uid=X4b8f331cb1dc6e1a Fleetwood_brougham_BLOWER_wont_turn_onbrougham BLOWER wont turn on?&content=&template={{title}} {{url}} (via @WikiAnswers)&lng=en&uid=X4b8f331cb1dc6e1a
Piston heater element open.
Low coolant level? Cooling system airbound? Bad thermostat? Water pump not circulating coolant? Heater control cable not working?
you dont have to if you turn it on it wont chrge it wont die turn it off in order for it to charge
since they both wont turn on, check to see if the fuse is burned out, a lot of times both the stereo and the controls for the heater are on the same fuse... if that is not it there could be a wire either broken or shorting out somewhere between the fuse box and the stereo/heater. also there is the possible coincidence that both the stereo and heater have quit at the same time... but I would check those things first.
Turning my ignition on and wont turn off because it is faulty.
