PBC codes

Not much to describe. It is inop. Lights show on each button but no response to any command except to test and go through sequence of codes. I removed pbc, opened, found all solder connections normal and no obvious defects. The car seems to have defaulted to max hot air from all dash vents and defrost. I can control nothing. When not in EC mode the a/c compressor works and forms frost on supply line, indicating it works, but with no fan and or vent control everything stills flows max hot. The system problem started as intermittent and has now gone full time over a two month span. It looks like I may have to cave and grovel at the MB dealer. Im tempted to throw a pbc at it but Im not convinced. What do you think? Doug
