I made a stupid mistake when installing my system. I spliced into the wrong wires under the dash for the front left spkrs. Org/Lt.grn & Lt.blue/Wht. Now my A/C doesn't work or the heater. I've checked the fuses, all good. I've checked the diode....all good. I've inspected the wires that were cut and the one's around them...all good. The guys at Pep Boys say it might be the blower. Well I've got air at all speeds, low.med.high, it's just that I can't get hot air out it or cold air out of my A/C. So someone told me that it might be the blend door motor, because it SUCKS! Bad manufacturing. But if I cut both those wires I said COULD that short or blow out the blend door? Hopefully someone is able to help me out. I'm in Cali and the nights here now are getting cold, so I need it. Thanks all.

12/16/02- Nevermind about this problem. I made the biggest bone head mistake I've ever made. I didn't re-connect the tempature control switch that's on my dash back into the wiring harness. So there was nothing to relay the tempature. I know, I'm stupid!!
