My buddy here has a 1990 325i BMW with an A/C problem. When the system
is charged and turned on, it runs for 4 or 5 minutes and can be felt
blowing cold air. Then there is a loud click-click up under the dash and
the air stops being cooled. I suspect this is the expansion valve acting
up, but don't know for sure. I have been told that is where the valve is
located, and if so - it appears to be a beast to get at - like the
heater motor on the Vanagon - the dash has to come out.

Can anyone confirm this? or tell me what they think of the situation and
what steps he might take to remedy the problem?

Thanks,

John
