another heater problem

Can anyone help me im in need of a wiring diagram for the heater sys in my 93 wagon. the hyanes manual says nothing about the eletrical part of this system. i know the heater core is good and as far as i can find the vacuume sys is good too but no heat. any help is is great.

Did you check to see if the blend door is opening?
Are both hoses going to the heater core hot?

were is the blend door located? but all vacuume seems to be working. at one time i had power to the temp swich but now theres nothing. i will check the blend door in the couple of days.

Check the steel heater hose coming out of the heater core going up the fire wall, they may be plugged. Ed

Does your wagon have the EATC (Electronic Automatic Temperature Control) or the manual system with knobs? If you have the manual system, the only power should be for the blower motor and the illumination (which only have power with the lights on). The rest of the dials and knobs control either vacuum or cables.

I can get you the electronic diagrams for either system, but don't want to spend a bunch of time saving off the wrong ones.

I have the maual controls and there are no cables its vacume and elitronic blend door opp. I have the hole heater box out at the moment so any testing on that may be easer, i took it out when i relized the heater core had a small leak. the wiring diag whould be nice.

I am having the same type of problem with my 03 ses. I thought that the therm knob actually had a problem since I jiggled it and the heat came on. But not anymore. What is the blend door? I know i probably sound like an idiot but I haven't done much with cars.
