Hi all,
I have been refered to the forum & i hope i get help.
I own a 300SE 90 model done 80000km.The a/c cools
for 10 min & then the compressor cuts off & does not
cut in again, restarting the car starts the a/c again,
for the time it works the cooling is perfect. I have changed
the following,

control unit
evaporator sensor
a/c relay
pressure switch

I would appreciate any help.
