The heat in my 91 acura teg isn't working. Turn the switch and no air what soever. Highway speeds a little bit comes out, but other than that nothing comes from the vents. Just replaced climate control assembly and still nothing. put power to the blower motor plug and it works. is there a blower motor relay and if so where the hell is it???????

 

Check the fuses....

 

already checked them, all good

 

blower resistor? Does it work on HIGH fan speed?

 

none of the speeds work. still can't find the blower motor relay

 

take the plug out of the fan while its set on high and see if it is getting close to 12 volts. If it is then you know it is the blower motor.

 

alright i'll try that and get at you a little later, thanks bro

 

ok. i checked the fan plug, with all of the speeds it reads 1/10 of a volt. doesn't seem right. the blower resistor is reading 2.5 ohms which is normal. from the fan plug to the other end of the wire where it meets the ignition switch, it has continuity, so there are no broken circuits. I AM CLUELESS!!!

 

yeah you are on the right track, if the one side had continuity to +12V the other should have continuity to ground (it doesn't get 12V so one of them should be open) just work your way back unitl you find 12V

 

i am not sure if honda has it...but on my old nissan i had...behind the fan controler lever there was a control board that controled how fast the fan ran, well that somehow got mostiure to it and would only let the fan run at full speed....then it eventually took a dump and wouldnt let the fan run at all..that could be your problem....i think the controler was only like 20 bucks?...but like i said i am not sure if Honda has that...it was on my Nissan
