QuestionQUESTION: Kevin, I talked with my mechanic a few minutes ago, ask him if he had tried a new resistor he said... no! Because, it needs a new blower motor and resistor.
That is part of what he needs to know...where is the resistor? What do you remove to get to it? And...how to remove the dash to get into the blower motor to remove it?
I was under the assumption that he thought...the resistor was at, or near the blower motor, that's why he needed to remove the dash, to replace resistor and motor at the same time.
If in your professional opinion, it's "only" the resistor that needs to be replaced, I know you will say so. But is it possible, I could know that today? The mechanic is picking the truck up tomorrow, or he said he was.
I had been unsuccessfully trying to get the information on the, "How To", so he could remove/replace, with good results. Until, you offered kindly to do it. I was surprised, because no one wanted to help with that, they seem to have varied reasons not to and maybe, understandably so. If your offer still stands I really would like to have the....How to. Realizing too, you said it would take several days to do it...that's all right, mechanic can wait, I will insist, until I receive it.
One last thing, the dealer on a call to them yesterday told me, I might better replace the heater core also....at their price of 320.00 for a core...I guess they would! They went from 700.00 to over 15000.00 and upward, in a short breath, to do it all, for me...how very nice of them.
If you need any more info, please let me know, I will be around all day. Thank you so much.

ANSWER: Here is the info for the blower motor resistor u can do this yourself its under the cowel panel I would try this first because the part is only 24 bucks at advanced auto parts.
BLOWER MOTOR RESISTOR
FRONT
REMOVAL
Disconnect and isolate the battery negative cable.
Remove the cowl plenum cover/grille panel from the cowl top. See Vacuum Reservoir in the Removal and Installation section of this group for the procedures.
Reach through the cowl plenum access hole Blower Motor Resistor Remove/Install to remove the two hex screws that secure the front blower motor resistor to the cowl plenum panel
Pull the front blower motor resistor and its wire harness out of the plenum panel and through the cowl plenum access hole far enough to access the wire harness connector.
Unplug the front blower motor resistor from the wire harness connector.
Remove the front blower motor resistor from the cowl plenum.
INSTALLATION
Plug the front blower motor resistor into the wire harness connector.
Install the front blower motor resistor to the cowl plenum panel by feeding the resistor and wire harness back through the cowl plenum access hole.

QUESTION: Kevin, I was not able to physically remove the resistor myself, although I did put a very good effort into it. I did locate it with your pic and instructions on, how to.
My mechanic picked the truck up this morning, along with your how to info. He just called to let me know the new resistor is in the truck, but...it still doesn't work! He said the connector and wire, was fine after he pulled the resistor out.
I sure could use your advise again. Do you think its the relay? I ask the mechanic to check the fuses, and to wait until I could contact you. He is bitting at the bit to, remove the dash. If he had the how to, I know he would. What do I do?
Where is the relay? He is wanting me to get the How To, on removal of the dash!
One last thing, I drove it about 50 miles yesteray, cold air was coming out of the vents, although very minimal, it showed me it was trying. There didn't seem to be hardly any blower action pushing the air out. Cold air did stop coming out, when I stopped at lights, but re-started when car was in motion.
If your able to give me info, I will be forever grateful to you. Mechanic is sitting on my truck, I feel helpless, don't know what to do.
Thank you for all your help, I really do appreciate it.
