Make sure ur car isn't overheating because ironically your heat goes away when the engine overheats.

 

So your switch wont turn on your blower motor right? It is possible that it is your blower motor resistor. Mine is going bad and my heat wont work on 1 or 2 only 3 and 4 and sometimes it doesnt work at all. The resistor can be picked up at a Honda dealer for around $30. I was quoted $27.70 for one by me. Hope this helps!!

 

does any air blow out of the vents at all cold or hot?

 

?! holly ****

 

car is not over heating, nuthing comes out of the vents at all on any setting . (its freakin freezeing in here mr. bigglesworth) lol Any other ideas thanx>>> evan

 

check up under the dash where the blower motor is for any loose connections or maybe some wires came unplugged, check thermostat, check for clogs in heater lines, and check fuses one more time, after that i would say its time to pull the dash out and get a closer look

 

there actually is some heat coming out now but not enuff, could it possibly be the blower resistor like vince said?

 

it is most likely the resistor... do a search and you could find a pic of where it is at and what it kinda looks like ... i do need to change mine

 

Its easy to find just take off the glovebox and right behind it is the blower motor housing right on top there is a little like rectangular black thing that has a harness going into it unplug the harness take the 2 little phillips head screws out and thats it.

 

my car was doing the same thing and it turned out to be the blower motor, and my car has AC so it was a PITA. i wouldnt want to do that again.

 

thanx guys im gonna f w/ it 2day

 

hey guys I lost my computer 4 awhile and now its back finally. Anyways sorry to bring this 1 back from the dead but its gettin cold in NY again and it still aint fixed but it has been narrowed down here goes
1. blower motor fan works when i give it direct power and ground otherwise it dont turn on
2. resistor is new
3. ground is good ( with this i gave 12 volts to the test light and put it to the ground of the plug that goes into the blower motor. I then turn the switch for the heat from off to on . As i turn it on the test light lit up and when i turned the switch off the test light bulb went out. Im assuming that would mean my switch is good on the heat console above the radio???

Any ideas guys it freezing in the morning and it s gettin worse
