Just go to any old MB dealer and buy the switch. Why is this a hard to find item?
I am getting ready to do a R134 conversion on this car, it lost the R-12
> charge. I went and bought an new receiver/dryer (no, it it not an
> accumulator) for it, and discovered that the electric fan pressure switch,
> which is mounted in the receiver/dryer, had been disconnected before I
> bought the car. A mechanic had inserted a jumper wire into the two leads
> that were connected to the switch to make the fan run...constantly now,
> whenever the A/C is turned, on I presume. This must have been done because
> the switch went bad, and they didn't want to have to do a recharge just to
> get a non-essential switch replaced.
> So now I am having trouble locating this pressure switch. Wonder if this

> Any downside to this, other than wearing the fan out quicker?
