Well, I just finished my B16 swap. Everything works perfectly fine except for the heater. For some reason, there is no electricity going to the heater control unit. Normally, a few lights are on.. I.E.... Circulating air/going to feet/front defroster. Well, the lights aren't on. I checked the fuse below the steering column and the fuse is still fine. I checked under the hood for the Heater Blower Motor fuse thing but that's fine as well.

Also, my rear defroster doesn't work either. Could there be a relation with to two not working? My main concern is the heater though. Please help!

CLIFF NOTES: Did swap and heater won't work. All fuses are fine. What's wrong?

During your swap, did you hit or pull any wires/connecters while plugging in the ecu? Look were the obd jumper connector is inside your car. See if anything looks loose or out of the ordinary. It happened to my friends car and he just fiddled around with wires and connectors in that area it worked again.

 

somethin came unplugged could be in you heater controls too

 

I jumped the heater blower motor and the motor seems to be working fine but my switches are not working at all. No lights, no nothing..

 

Is a/c installed on the swap?? Check relays, fuses, bad switches.

 

No, I don't have A/C. I removed the whole system. All fuses are fine. I checked the fuse under the dash (heater/rear defroster/somethign else) and 2 other fuses under the hood, one being the heater blower fuse. It just seems like the climate control unit isn't receiving power and I'm not sure why.

 

did u check around the ecu area?
