2001 honda civic lx-I started the engine ,turned on a/c, to cool car off because it's 100+ degrees today and the a/c came on for a few seconds and for those few seconds it blew unusually cold, for it not to have been running at all today ,than it just quit,so no a/c- no heat- and no blower motor "What happenend"Iv never had a problem with the a/c before, car has 105558 miles on it if it helps, "Please Help"?-cz
-------------------------
You mean the fan stopped blowing "any" air? then your blower motor resistor probably went, it's just downstream of the blower motor which keeps it cool..check fuse first, and also if there is a blower motor relay, not sure.. But if you lost all speeds, it's most likely the resistor....

2001 honda civic lx- Will the a/c commpessor not work if I have a bad blower motor resister?and is the resister you are refering to under the glove box with the heat sink attached to it? 1 ohm? or somthing like that-cz
-------------------------
The system has a power transistor instead of a resistor but the concept is the same. The control panel drives the power transistor, which is mounted in the duct behind the glove box, to control blower speed. The transistors do go bad, and then the blower won't run at all. But also check the motor first. If you have 12 volts between the motor leads but it doesn't run, the motor is bad. If there is zero volts between the motor leads, but both leads are at 12 volts relative to ground, the transistor is probably bad.
will a bad resistor keep the compressor clutch from engaging?
-------------------------
I'm not sure. The control panel has a computer in it, and it can detect trouble situations.
There is a way to press the buttons and get trouble codes out of it but I don't remember the exact sequence. Most often the problem has been the power transistor or the fan motor and not the control panel itself.
