There is winter in Israel now but far away from 4C
I think something like 12-17C

Yesterday I came to the dealer and they checked freon level and it was fine . Sometime it work and sometime it not ... for now it work...

Intermittent electrical fun ! Currently the auto climate control is sending the correct voltage & I have to assume it'* the intermittent wiring /pigtail issue.
The heat from the engine/ exhaust cooks all the pigtail wiring over many years. It took me about 1.25 hours to fix it, with the correct part.
It'* a matter of carefully tracing the wires back though the split loom tubing to remove all the bad & install the new.
Heat shrink tubing, solder and larger split loom tubing was involved here.
I also used new split loom tubing that was smaller in diameter to protect the new pigtail back to join into the 2 main wires involved

Hi everyone
I did an electric test and found that the AC cluch relay don't get a -12vdc in 86 pin , from the schematic draw the pressure switch need to supply it .
What is the next step to found the problem ?

Check fuse #26 -I like to confirm with a VOM/continuity that it is a good working fuse.
The A/C Relay is #32.
For testing purposes you can use the relay beside it- swap them around move # 31 to # 32... & 32 back to 31.
See if this helps..

Thank you
I already tried to swap between them and it'* not worked .
the fuse is OK , in addition , I conected a wire with 30 and 87 and the cluch engaged .
the relay don't get -12vdc from the pressure switch , how can I test it ? In the plug I saw 3 wires

Fine? Without actually knowing what the refrigerant high & low side psi specs are currently reading form your car, it could still be low on refrigerant.

There are only two things that I can think of that may cause the lack power reaching the AC clutch.
1-Low on refrigerant
2- Broken or intermittent wring somewhere along the green wire, connector/pigtail.

I suspect the low-pressure switch.

This thread is getting old, but tere is no separate low pressure switch on this particular year. It has one transducer located on the compressor that detects both high & low side pressure. If refrigerant is low, the compressor will not engage!

Ah okay. I didn't know they changed back then.

Today I checked the freon pressure , totaly ok .
I noticed for something else but I am not sure , only after the car very warm (+93 celcius) the clutch engage (outside temperature was 18-22 celcius)
any help ?
