A/C controll question

MattLopez15 · 09-30-2009

My and A/C blows cold and my heat is fine as well but it wont work unless i have the (for lack of a better word) "intensity" set to the 3rd or 4th dot. does any one know what could be broken? thanks in advance

Similiar problem with my 01'. AC blower only works on high. Have swapped motors, not it! I changed the dash control selector/switch, nope, not it either! I'm hearing about a resistor but not sure of location or what to do with it, replace it, hit it(as others state), test it with a meter? Anyone want to chime on in here for us?

i know that sometimes the heater/a/c gets stuck on defrost.. and that problem is caused by a leaking vacuum hose.. possibly a similar problem for the intensity? though thinking about it more i get the feeling itd probably be an electrical problem

yah, i wanna say its an electrical problem because every thing is coming out at the temperature it should be. i was just looking for some general advice before i start taking things apart

. but what is a resistor? and what would it look like?

Good news boys and girls! AC is working properly again. Replaced blower motor resistor with new one from O Reilly. Located under the dash behind glovebox, cost about 20 bucks. Thought you might like to know.

lucky! was it hard to replace? and i just might have to do the same this weekend

Easy as pie

Nice for everything to work again without blasting ya out on high.

took me all of 10 mins to get to the resistor (my Haynes repair manual helped me) and sure enough, its one big rust ball and one of the wires has snapped off. advance auto is over night shipping me a new one for $20.13. thank you all for your help
