Climate control unit bypass

Hi, I've got a '97 prelude and my climate control doesn't work(no green lights defrost works but no green light), I checked all the fuses they're all good, same with the relays, I'm pretty sure the issue is the actual climate control module itself, now I was wondering if it was possible to safely hotwire the blower to an (on/off) switch and I was looking at the wiring diagram and cannot figure out how to do this. here is a link to the wiring diagram I've been using

On page 60 you can see the resistor along with 3 wires going to the 'heater fan switch' I think one of them needs to be connected with another in order for the 'fan' to run cant figure out which one's it actually is id like it on off at full speed. any help would be greatly appreciated.

turns out I troubleshooted the blower motor 2 pin connector and there is no power, so ATM I'm testing the relay, I doubt the relay is the issue but who knows. ill keep this thread updated.

Re: Climate control unit bypass

ok, so i got it to work!! here's what i did and what you can do if you have a similar issue. remove glovebox, look for the 2 pin connector that goes into the blower motor, there will be a red/blue wire (#2) that's the ground, take a jumpwire (any wire big enough for high amp) and stuff it into the part where the red/blue wire enters the connector, then ground that wire to the frame and it should work(might have to turn ignition key to the on position), if it doesn't unplug the connector from the blower motor and with a multimeter check for 12v on pin #1 in my case i had no power, so i traced back to the relay under the dash fusebox and tested the relay, it was good. so after this step the service manul says to check for power on the #4 pin of the relay socket for 12v when ignition is on, i had none, troubleshoot then sais the issue is a faulty fusebox... but it turned out the R/C mirror fuse #9 underdash fusebox was blown, i had already checked it but it was dark and must of miss seen. i replaced it and climate control now works. but yea to hotwire the blower all you have to do is to jump the red/blue wire that goes into the blower motor to ground, id put a 7.5amp fuse on the wire along with a switch and it should work.
