Fuse #5 in the dash near the door protects the vacuum pump and speed sensitive steering. My vacuum pump is on the fritz and this is what I believe caused it. :D ht...

All V8 XC90s have variable displacement compressors. There is a solenoid on the compressor to control the displacement that is operated by the ECM. The solenoids do fail and the compressor can have no pumping or less than full pumping when the solenoid binds and does regulated pressure in compressor...

CEM water intrusion is an 05 up issue for P2. Really just 05 and 06 as they did some modes to improve sealing. The change for 05 had the top of CEM coming through the opening under cowl cover. Ice forming and then thawing at the opening due to interior heat was a major cause. The 04 down P2 CEM was ...
