After testing all the fittings on the vacuum distribution/control box leading to the vac actuators two of them tested bad. Lines are good but diaphragms are bad.

Anyways I was able swap the one pretty easy but how about the actuator that controls the cabin air recycling flap? Does a guy need to pull the crash pad/dash to remove it?

Yes. I had to replace the same actuator our 1995 C280. It is completely inaccessible without pulling the dash.

Thanks my friend.. Kinda looked that way but wanted to be sure before putting that kind of effort in. Anything else on the list while the dash/crash pad is off? Half temped to swap all the vac actuators.

I can't think of anything other than looking carefully at everything looking for broken plastic, etc. I have never had to replace an actuator for a diaphragm problem. The problem I had was the return spring for that flap/actuator broke.

I'll be looking into that as well. Thanks again.
