Question about BMW 525
Check the pressure on the low and high side " with a meter " and low side should be around 45, high side should be around 250 - 300 if it's over 300 there is an obstruction if it's less it needs more freon.
also you have flaper motors that are either electrical or by vacuum.
and i think it's a vacuum problem because of the year model.
they aren't switching from warm to cold.
take the climate control module out and look for any un-hoocked rubbery line or a broken one
