Does anyone have the repair manual for HVAC issues? More specially 2008 IS250 drivers side servo motor replacements. I was only getting cold air on the drivers side as the servo seemed stuck or broken. I took apart all the panels under the steering wheel and was able to view 3 servos that are what seems to be connected to one plate. I believe it was stuck because once I took it off the plate I could see all the servos moving. But now I'm having an issue putting the plate back on as I can't line up all the gears. Hoping the repair manual will give clear instructions on how to put it back on.
