My haynes manual shows an orange and black wire comming from the resister, to the blower motor. Then on the other side of the circuit it shows a brown and yellow wire leaving the blower motor going to the relay. Then it has a black nd light green wire going from the relay to a 40 amp fuse # 23 in the power distribution box. But it nor my owners manual shows where the relay is. My owners manual is for a 97.
My haynes says it is good through 2002. But the schmeatics look different from the ones previously posted. That's all I've got. Hope it helps.

Nobody has told us yet where the elusive Auxiliary Relay Box #4 is. One member said to look in the factory service manual, that's the only clue so far..................

Actually, I said that is where it is referenced which was your explicit question. The FSM only gives its location as "behind dash panel, center". The blower motor relay shares the box with the flasher relay for the turn signals/flashers. Turn on the turn signal and follow the clicking noise to locate the "box".

Go back to my very first post in this thread and follow the simple steps I gave. There is zero indication in any of your subsequent posts that you did that, instead it appears that you are still messing with the low side of the circuit without check the power side first.

Pinpoint test M will tell you to check for power at the blower connector with the system powered on first. If no power is found, it will direct your towards F105 and the blower relay circuit for further diagnosis. If battery power power is present at the blower connector in step 1, it will direct you to make a resistance check of the low side of the circuit through the speed switch while set on high. If that test passes, the blower motor is condemned. I gave a streamlined procedure.

Found aux relay number 4 changed relay and resistor still doesn't work ... Is it possible the speed selector switch could be bad

Are you EVER going to perform the tests I gave or are you going to continue screwing around, wasting your time and ours?

If all you are going to do is to waste time, and money by throw parts at it until you get lucky, throw a blower motor at it.

Have you even read your own thread. That has been suggested several times.
Take a look at post #25. I didn't look back further, but I think someone suggested that before then.

Hmm - with that outburst, I don't think you are going to get much more help here. You may want to start over from square 1 on a different forum........

Calling experienced techs useless and retarded is no way to win friends.
