A/C Control Unit Problems. Wiring schematics needed.

Hey guys. Well my cooling for my air has been messed up for about 2 weeks now and I'm trying to figure out the wiring and what not. Does anyone happen to have access to a 1996 Honda accord wiring for the A/C Control Unit.

I'm not sure how air conditioning wiring is done since it seems really confusing right now. I have the normal air running and everything but it doesn't go to heat or cooling, I can't figure out why. The A/C Control Unit circuit board fried at two parts on it. I need some help with it.

I can always just bypass those with wires and what not, but does anyone know where I can buy just the circuit board? I've been searching for months and can't find any. I've been to plenty of junkyards but I can never find the 94-97 generation units and I tried a previous generation since wiring colors were all the same but it didn't work completely. If someone can help it'd be great.

I don't think you can buy just the circuit board.
The only place you can buy it is probably the dealer and they want to sell you the whole control unit.
Other place you can buy it is auto salvage house. Again, it a complete unit.
Wandering the junkyard and hopefully one day, you hit your pot of gold.

In the mean time, jump the wire to see if it works. Look like the cuircuit is overload and burn.

Yeah I jumped it two days ago and it's working fine. I'll keep it until I can find another board. Hopefully more 94-97 gens come into the junkyards around here and I can get one.

Have you searched junk-yards online? If not, try www.car-part.com and search for Heater/AC control. I only glanced over the search results and saw some as low as $25. They may be even cheaper but as you get towards the end of the list they won't list the price, you'd have to call. I ordered a new climate control unit for my QX4 and it cost me about $55 and $15 for shipping and they included the whole radio bezel and wiring harnesses.

Yeah, I was searching through some of those sites but I'm not a huge fan of online ordering but I did find a car parting place around here that is somewhat similar to that site. Thanks.
