Brian, Good question. I belive the recirc "small lift" is dead on this car, allowing 10% outside air, but not allowing 100% recirculation either. Regardless, if there was excess load due to warm air, or if the evap was dirty, AND the cutoff was normal (mid/low 40's), the compressor would never cut off or cycle. It would stay in the 50-ish range and not cycle. The fact that it cycles proves (to me, anyway) that the cutoff temp was too high. I'll be replacing all the pods on this car soon - just received them from Rusty two days ago.
BTW - the diverter would normally operate some of the time, on & off, when the AC is engaged. This car has a dead diverter pod as well as center vent, so I'm measuring from the side vents. The temp difference would be minimal though. After all the pods are replaced I'll re-test the system to make sure temps aren't too cold. :-) -Dave M. > ---------------------------------------------------------------------- > Date: Fri, 12 Aug 2005 07:52:47 -0500 > From: brian toscano <[EMAIL PROTECTED]> > Subject: Re: [MBZ] W124 A/C question - compressor cuts off too soon? > > Dave, > > What is the chance that the recirc flap is not closing all the way > allowing 100% outside air.
