Hi my name Is ***** ***** I will try and help you as much as possible. Have you replaced the cabin filters in the suburbans?
ok then it probably came without them. next thing to check is restriction at the front of the condenser. the condenser is located in front of the radiator. make sure it doesnt have any debri or dirt restricting air flow
ok, lets try this. with the engine off, key on. move the temp select knob from cold to warm then warm to cold and you should be able to hear the blend door actuator moving.
5 seconds in each direction?
theres a history on those 2 years of the compressors leaking very little. they are actually a four piece component and the four mounting bolts if not properly tightened to torque spec will cause a small leak over time. not saying thats the problem, but worth checking out. also i would advise you to have the complete system properly evacuated to remove any dirt and moisture then have them reservice with new refrigerant.
close off all the vents in the vehicle except for second row. see how much the air flow increases
if that fan is loud it means the bearings are going bad and isnt putting out the required flow
ill send you instruction later. gotta get my butt out of this shop...been here 14 hours already
its easy to replace. just remove the right rear trim panel and youll see the fan. theres only a few screws and a connector
let me know how it turns out
allow me to get back to you in a bit...thanks
there dont appear to be any filters back there but there are foam seals that attach to the ends of the ducting where they connect to the case. alot of time they disintegrate and need to be replaced. they are available any longer from, anywhere but you can get some foam material with double sided tape and make your own
