Battery Drain

Post by bats1 »

Help! This may sound like I'm going nuts, because I am. My '03 XC-90 2.5T battery continues to drain. I've checked all fuses (good), current/voltage drops (none), changed a couple of relays (in desperation), battery checked at two different locations (second opinion) all to no avail. What I have noticed is that the rear window heater light intermittently illuminates and the heater blower motor increases to a high speed, and door locks/window controls stop working. In the absence of wiring diagrams, I am a loss. Have not taken vehicle to Volvo mechanic due to not having the budget to do so. Anyone out there have any ideas?
