Outside temperature shorting...
« on: 22 June 2022, 17:38:00 »

Hello guys,

First of all, sorry for my choppy english, but I still hope you'll understand me  :o

Got my a/c compressor fixed and was enjoying cool air this hot summer and suddenly it stopped working. (compressor got into a on/off loop, "My Naff Code Reader" showed A/C Cutoff mode active/inactive infinite loop and 171 outside temperature sensor voltage high.
Bought a new sensor, same problem persists, checked the connection behind drivers side light (where fog lights and that sensor connector is) the problem still persists, tried other sensors from working cars (other omega and opel astra h) with working a/c's still same problem, so i came to conclusion that wires are somewhere damaged and I tought its better to just run new ones along, but I don't know where they go to.

Blue wire is 5volts, the other blue with white stripe is signlas i guess?

All help is appreciated, I need saving from this heat  :'(

Worth checking the loom one the bumper side, as they often corrode there.  Also, the loom can corrode on the exposed bit where it hangs new the horns.

I'll dig out where it goes beyond that in a bit.

It goes to connector X1 (Front A post Footwell, left side), pins 10 (Blue) and 67 (Blue/White).  From there, Blue/white goes straight to TID/MID/GID/CID pin 2, Blue goes to TID/MID/GID/CID pin 3 and Climate Panel Pin 8 on larger connector (X63)

Found it, now temperature is good, but still, a/c wont turn on. No more fault codes only A/C cutoff mode is still active.

In which case either too much or too little refrigerant  ;)

Or a duff pressure switch.

Where are those pressure switches? are they somekind of sensors? maybe they're broken too  :o :o

On the V6, it screws into the line that runs past the front of the engine. Looks like a stubby cylinder with a rectangular plug on the rear face. Screws into a union on the AC pipe.

Should be in a similar place on the diesel as the plumbing is similarly routed.
