E-30 airconditioning question

[Scott52295@xxxxxxx]

I have a 1986 325 (it does not have the "e" on the trunk badge, but does have 
an eta engine).  Recently the air conditioner system has been blowing 
unchilled air while driving at low speeds and while Idling.  After a trip to 
the A/C shop, I am told that the condenser fan is not functioning, and the 
pressures seem high.  It is not leaking.  When I got it home, I checked the 
obvious things - fuses etc.-All re O.K. When I started it next the fan came 
on and operated correctly.  The next time it wouldn't come on at all.  An 
intermittent electrical fault is my tentative diagnosis.  The A/C put out 
lots of COLD air at normal cruising speed 75-80 mph.  I guess the ram air is 
enough to carry away the heat from the condenser.  Does anyone have any ideas 
on where to look for bad switches, relays, etc., or other possible culprits?  
My BMW repair books are remarkably vague about A/C systems on theses things.  
Any help will be appreciated.  Please e-mail me privately at   
<<Scott52295@domain.elided>> to avoid WOB.

Thanks!!

(I know the proper fix for this A/C problem is to stop whining and just drive 
fast.  Unfortunately, my wife and the local law enforcement community seem to 
have problems with this eminently logical approach.) ....grin....
