Is the situation the same on a 1991 190e? I understand there are five vacuum modules and if I change one, I should change them all. Can I do this without removing the dash? Also my blower has stopped spinning even though I get cold air out of the vents as I drive down the highway. I'm assuming I'll have to replace the blower and hope I can change that without removing the dash. Lastly, I get a fog blowing from the vents into the cockpit. Is there an easy way I can tell if the evaporator is leaking or if it is just condensation? I've never had that on any other car I've had with A/C before.

Thanks
