W124 260E 88' climate control problems.

[cjkuhn]

Hi all.

Maybe someone can help me with the problem I'm having as I've hit a brick wall

I've done the test from the post on peachparts testing all the pins leading to the klima relay and everything checks out except pin 10 it gives a mere 0.3v when testing.

I thought it might be the pressure sensor but jumping it still gives the same result leaving me with pbu.

Does anyone here know what to check on this thing or how to bypass the electronics of it so that I just use the switches seeing it would cost me 25k to get a new one and a waiting period of 6 months

Any help would be appreciated.

Thanks
