Wiring Diagram - A/C circuit for 90SC

Hi Everyone,

Does anyone have a wiring diagram for the A/C circuit on a 90SC????

A/C clutch won't engage, even with the low pressure switch bypassed (I know I'm a bit shy of charge - but the compressor should engage regardless).

No blown fuses - and no voltage out to the A/C compressor clutch connector when the A/C is engaged.

I'm thinking it must be a relay somewhere that is shot. I have a Haynes manual, but they are useless for wiring diagrams.

Thanks.....Greg
 
Clutch

Read the resistance of the clutch coil, and see if it is good or not.
You might put 12 directly on it to see if it engages. The other possibility might be the Wide open throttle cutout relay is stuck?
I have a electro clutch if you need one.
 
Re: Clutch

Thanks Peter - The clutch coil seems ok - I put 12v to it and the clutch engaged. I think it may be the ICM (integrated control module) which is shot.

I have the diagrams, but I am pretty busy to study them and give you more suggestions.
I have a spare ICRM you could try, and I could make copies of the Drawings, but you would have to come and get them/it.
I am in Etobicoke.
