Hi all need to know if the compressor control unit next to the fuel relay
controls just the compressor ?.
As the dialled temp of 20 C approaches the centre vents air all gets
diverted to the screen. Should it not go the side vents and then come back
as the temp deviates?

About jumping ac clutch; please unplug ac spade lug connector before
applying voltage to test clutch; i applied voltage to + side with engine
running, climate control on & it burned a trace off my climate control
circuit board; after a lot of other checking; finally found a blown fuse,
on a/c?? or OVERLOAD relay under pass. side of dash; pull lower panel &
look (or feel up at right side) for relay; pull relay out & check fuse,
mine was blown; on 85 300D; not sure if yours has this overload relay or
not; hope this helps a bit???; Steve
another thing; it is possible to hook climate control UPSIDE DOWN, & plug
in; this will blow out your TEMP. control module
