Usually can find them in digital format on Ebay, or Amazon.... those are fairly cheap. The print versions are available from Bishko, (the publisher) but, them fellers certainly ain't cheap.

 

I downloaded a manual, but does not show hoses on the firewall, only a/c lines and routing underframe to the rear.

OK guys got it plumbed, but the rear AUX. water pump is not activating off of the front or rear controls, (I can out power to it, and it does work) but I cannot locate a fuse for it in the vehicle or the service manual, can anybody tell me where it gets its power from? really don't want to hot wire and add a new toggle switch, which I can to get power to it but really want to keep it original.
Thanks in advance

Rear blower is powered via a relay fed from fuse K, 25 amp, in the PDC, should be hot at all times. Relay control is powered by fuse 24, 15 amp, also in the PDC. (hot in run only) It looks like the relay itself is not controlled at all, and is simply 'on' with ignition on.... Rear blower switch simply controls the ground path. That would imply that the blower motor should be seeing power at all times when the ignition is on.

 

blower motor works fine, it is the auxiliary water pump for the rear heater that I was referring to. Thanks

 

DOH!

Lemme see if I can find that.

Found it. Pump is power via the A/C control head in the dash. Orange/Lt. Blue wire, C2, pin 10.

Not sure if I am reading it right, but, according to the wiring diagram, it appears the HVAC Controller is powered from the front blower motor.... Fuse 13 in the PDC, 40 amp.....

 

all of that checked good, gotta dig deeper i guess, mabe it is a actuator or something.
but thanks for the info, going to take rear assm apart and test stuff

 

Are you getting pump power OUT of the control head???
