A/C dead, relay change?
hey Folks,
my Aircondition doesnt work. (cargo 97' 330cui)
description:
-turned the Switch= nothing happens
-went to my friend, filled and tested the System. it wasnt empty, no pressure loss nothing.
-bypassed the pressure Switch, nothing happens.
-then removed the plug from the A/C compressor and give the magnetic clutch 12V via external battery. it works.
-started the engine with the closed clutch.
-very cold into 1 Minute
so i belive in a relay that gives power to the magnetic clutch. where is this relay ? i checked haynes rep. man. but the wiring diagram wasnt a help
maybe the Switch in the Cockpit is dead?
would be thankful for some ideas!

Owner's manual here for free:
Owner Manuals | fleet.ford.com
Should have the relay location to see if the switch or relay is the problem.

There is a A/C Comp Clutch Relay listed at NAPA Auto Parts online. ECH AR671 for $18.49, it's fairly small and looks like it could be inline on the Wire Harness somewhere. And I found a A/C Control Relay ECH AR272 that looks like it's in a Fuse Block or Power Dist Box $16.49..........

Wide open throttle. The AC compressor shuts off when you put your foot on the floor to give a bit more engine power.

Since you're doing much of your own electrical diagnosis and repair I'd strongly recommend buying a factory manual or EVTM for your year van body/chassis.
Along with showing the actual wiring paths there are component location guides to show you here different things are actually located.
Here in the USA AutoZone has free schematics but you have to register which is very easy pain free.

The schematic you need might be available free of charge through Autozone.com. You'll have to register (give them an email address) but afterwards you'd have access to their library.
PM me about sending you an EVTM---glad to do it for anyone in need of service documents, especially not living in the USA.
