I need a little help with a 2004 Honda Civic Value Pack.
The blower motor is running all the time, could it be the climate control panel the faulty part?
I do not want to spend way over $150+++ and not fix the car.
I was driving on a heavy rain, I had every possible electric device turned on, A/C, radio, lights, wipers, etc.
Suddenly the A/C stopped working.
I though maybe a fuse blew up because an overload but after checking all the relevant fuses and relays both under the hood and on the inside of the car all the fuses/relays were OK.
Keeping troubleshooting I got to the blower motor transistor.
Inside it, there is thermal fuse that was gone, I think it was rated at something like 112°F/2 Amp. The main fuse for the blower motor circuit is 10 Amp so I think the 2 Amp may be a little under rated but who knows.
In any case, I could not find the original thermal fuse so I replaced it with what I could find (120°F/10 Amp, I know 10 Amp is very high as compared to the original 2 Amp but that is the best I could do, the "main" line for that circuit is also a 10 Amp and I think the thermal fuse is there for the temp, not the current really.)
Anyway, I though that would fix the whole issue with the A/C but it did not completely.
Now the current problem is that the blower motor starts running as soon as the ignition switch is the II position (for accessories, like the radio, etc.) Even with the climate control switch in the OFF position.
I replaced the blower transistor ($15.00) too but still the blower motor is always running as soon as the ignition switch starts or is set to the II position (accessories, like the radio, etc.)
The Diagnostic Test for the A/C unit blinks 12 times, telling me that there is a problem with the blower motor circuit but I really think that the problem is with the EEPROM in the climate control panel.
I already removed it but there is no way for me to test it, it cost way over $150+ and I do not really want to spend that kind of cash, not knowing for sure if that will fix the problem. In some places the climate control panel cost close to $400.00, other places I have called have them for $250 + 7% tax, etc.
My only question is if anyone has gone through something similar and can verify for me what are the chances that the climate control panel may have a failure or what other possible thing I could check before buying the climate control panel.
Thanks for the help.
