'88 560SL (R107); is it necessary to remove instrument panel to R/R expansion valve?
It looks like I have a clogged expansion valve on my ACC, the compressor works but the low side draws about 7 PSI of vacuum with a full charge (high side spikes after startup but settles at 130 or so). I replaced the receiver dryer hoping it was the point of constriction but now it does the same thing and when trying to blow air through the TXV line all I got was a small flow...looking at the CD it looks like MB says to remove the steering wheel and instrument panel to get to it...is there any way to get at it from below or is it absolutely necessary to remove those to get to it?

Instrument "cluster" YES..instrument panel NO..
You also have to be a contortionist to un-blot the valve.

My Faux Paux...yes, instrument cluster...
do you happen to know if the screen at the expansion valve inlet is removable for cleaning?
