Hi all,
My car always had problems with the AC, if you were in traffic the AC wouldn't blow cold air, but in the highway it did.
I tried looking into it and I found out that the AC fan was not turning on. I looked into the relays, fuses and finally into the wiring. After cleaning all the connections and specially the grounds, the fan now turns on.
I have to mention that one connector had signs of high temperature, like it had a short circuit at some point.
I did a very dumb mistake, when I was figuring out what was the problem I tried bypassing the relay and instead of bypassing the relay, I connected the control signal to ground. I'm not sure if I did it just on the fan, on the AC clutch or if in both.

Now what is happening is that the AC fan and compressor relay always have the 14v signal, so even if the AC is off, both have the signal. Also, if I connect both relays, just the fan turns on, if I only connect the AC clutch relay it stays engaged even if the AC is turn off and the blower motor is off.
I measured the resistance between the control pins for the relays and for the AC fan, and other, is 52k ohms, but for the compressor clutch the resistance is basically an open circuit. I checked the fuse 17 and is ok.
​​​​​​I've been trying to search into the problem and I see that the A17 pin might be the problem, but I don't know what to look for in the ECU.
