JDM Climate Control Blower Problem
First of all, I've looked in most of the JDM Climate Control topics and I have find some people with the same problem, but they havent say how they solve it.
I have made the conversion, everything works fine except for the blower (and the A/C I dont know).
Some times the control unit blinks, and if I play with the temp the blinking stops.
Any idea of what could be causing it?
The problem with the blower is that with the unit not work. I have tested the voltages with the IG on, the #3 BLU/ORN (20 pin) have almost 12v and it shold be ground, the #9 WHT/BLU (16 pin) is ground and should have voltage, and the #1 BLU/RED (16 pin) have almost 12v and it should be ground or at least much less than 12v.
I was frustrated and decided to remove the pins, and for mistake I left the IG on, and removed the 20 pin, and with the 16 pin in the unit (the unit was off), the blower start to blow not at high speed but works. I tested the #9 WHT/BLU (16 pin) and it haved like 1.4v and the #1 BLU/RED (16 pin) have like 5.6v.
I connected the 20 pins, just from above (not full contact), and changes to high speed (the unit still off). Then I insert the pin full inside and the blower stopped.
I remove all the pins, and connect just the needed to the unit to power on and the needed for the blower, test it and nothing, test it again with the 16 pin (#9 WHT/BLU and #1 BLU/RED) alone, and the blower works at middle speed.
Then connecting some wires of the 20 pins, #3 BLU/ORN, #13 BLK/YEL, #16 BLK, Then I started to play with the #16 BLK and the blower start at full speed but the unit off, and removed the #16 and the turn to middle speed. I think that the same happens if I left the #16 in and take out the #13.
Any idea of what could be causing this problem? or what corrections should I make?
I have followed all the diagrams, pin outs, everything and just have that problem.
I havent connected the sensors yet.
The unit have a -1.5v | +1.5v switch in the bottom any idea for what it is?
