So if you have rear heat, that would imply you have 3rd rows in the Gen I...?

I'd love to see any pics you can do of the setup. Any idea how it is ducted? what about controls for it?

I think I have an extra motor myself, if I can't get the one pulled.

What are 3d rows? I will be happy to send pics in the coming days when the fogs lets up enough to see the vehicle. I have not taken the rear assembly apart yet but can do it if you are interested. The dealer told me that the part number of the rear motor is different but he does not know for sure.

I have a rear on off switch built into console (Factory) and have found two hoses that run to the rear system and back. Let me know how I can help.

It's mounted near the blower motor. It is number 6 in the following illustration:



Here's what it looks like close-up:




If you don't already have it, you can get the FSM here: FSM link

99% of the time if the blower motor resistor failed it will only work on high. other 3 speeds will have nothing.

I'm now at home and have the schematic.... Try this first:

1) With the key switch in the RUN position, turn the fan switch to "High". You should see 12v or so at the blower motor connector.

2) Turn the blower switch to M2, M1 and Low positions and read each voltage individually. Voltage should drop each time you switch to a lower fan speed..... if not, the resistor pack or the switch is bad.

3) If there is 12v in the High position, but nothing in the lower speed positions, check for voltage at the switch terminals. No voltage on one of those terminals when selected by the switch indicates a blown switch.

4) If the switch and resistor pack are ok, the blower motor may not be well grounded - or it may have an open winding. To check, apply 12v (+) and (-) directly to the blower terminals and see if it runs. If it does not, the blower motor is bad.

that explains alot... my first 2 setting dont do anything. i have a choice of super hot or cold. not familiar with that relay... is it difficult to get to? cause if i gotta pull the dash, im just fine with the status quo.
btw partrick... can you just hear the drooling? you have no idea of what youve gotten yourself into. from some of the reply posts youd think youd posted monty porn... but then again mabey you have with the gen I 3rd row tease.

theyre usually not too hard to get at. ill try to remember to take a look at my 87 when i get home.

Nope, you go in from underneath the glove box. Might have to move the ECU, other than that it's very straightforward (other than the twisting, turning, lying upside down positions you may need to assume <img src="/forums/images/graemlins/lol.gif" alt="" />)

That is correct on my 89. Remove the ECU then two screws that hold the ECU bracket. You do not have to remove everything as shown in diagram.

whoa hey whoa there patrick... dont be going off topic by staying on topic. FOR THE LOVE OF GOD MAN, WHERES THE MONTY PRON <img src="/forums/images/graemlins/lol.gif" alt="" />! seriously though, post some pics... rear heat? im so jealous. back on/off topic... thanks guys gives me something to do when i dont have anything to do. will probably wait awhile though... winters coming and the heater will be taken off of stun and set to kill.
