Hey guys, running into some issues with my crx climate control. It is stuck in the recirculate position and will not change to fresh air. I have 3 different climate controls, and all 3 are like this, recirculate only. It's not a huge deal as I prefer recirculated air, HOWEVER I want it to work properly.

I have already looked through the helms manual pages 15/6-15/24. If I hook up the motor directly it works as it should. To add to this, I have 2 sets of control box motors and both work when hooked up directly to a power source, but when selecting it from the climate control, it does not work.

If I put it into the fresh air position directly by hooking it up to the battery, and then via the climate control select recirculate, it will work as it should...

If you look at the diagram below you can see how the fresh/recirc. motor works when connected directly. The recirculate wire goes to pin 11 while the fresh air goes to pin 5 on the back of the climate control. Now just like the function control motor which is ground switch operated, it should have continuity at those pins, when the respective button is pressed, between that pin and pin 13. Now I get continuity between pin 11 and 13 on recirculate, but not between pins 5 and 13 when on fresh air.

I'm pretty stumped in trying to pinpoint where the problem lies, because clearly it's more than likely in the control where there are no blueprint schematics of the electronic control board. Does anyone else have this same issue, and have you fixed it? Any help would be greatly appreciated!

 

wtf you have this in the sedan ????? umm interesting bro it could be one of the resitors on the board bro my friend fixes **** like this for an arcade he was able to fix my old sony amp and radio for free he just replaces alot of **** umm pm or txt at 9098277485 i might be interested on buying or trading a climate control with the control box and harness lmk

 

Not yet, it will be going in the sedan soon though.

I've been learning about electronics lately, but this **** has me hella confused since the switches for the selection have 6 pins each on them. 4 of the pins are the same and actually have continuity between them, 2 are totally different, but I can't pinpoint where the problem lies.

The controls I have are not great condition, you might get away with a faceplate on one, the other is garbage, and the best one I fixed and am using. BTW, there is no "control box" for the CRX climate control, I'm sure you got that from that idiot gnxpro from the fs section. That box has nothing to do with the climate control. The wiring is direct from the control to the motors it doesn't integrate into any "brain" it's all just ground switched via the control itself.

 

well i meant the motors bro

 

fo sho, I haz them :p You're lucky you don't have cruise control, the CC brain mounts where the function control motor mounts.

 

That was the quickest I've ever gotten help and solved an issue on HT! Thanks to a great guy from the other side of the pond, it's now working

 

how did you fix it? and btw i put cruise control on my crx and just mounted the brain wherever it fit

 

The guys a frickin genius haha

 

My dumbass didn't have 12v running to the controller, the way the crx climate control gets power is via the AC plug, the controller worked for everything else, so I never even thought about 12v to the controller. Well he mentioned if I've checked that and I at first thought the controller doesn't receive 12v, does it? But none of the lights were on on the controller or in my head for that matter. Looked at the schematic, got the 12v hooked up, lights on and the controller worked as it should.

Regarding the cruise brain, I like everything to be as close to stock as possible, idk what I'm gonna do but I'm sure I will figure it out.
