I have a 2007...

I have a 2007 Tacoma prerunner. For a couple years the AC/Heater blower has only run on high. Today it does not run at all.

Mechanic's Assistant: Have you checked the coolant level? Has there been any leaking from the hoses?

Its the blower fan, does coolant level realy effect that?

Mechanic's Assistant: Are you fixing your Tacoma yourself? What have you tried so far?

Nothing so far. Have read about a resistor that fails causing the fan to only run on high. But today that does not even work, maybe a fuse?

Ok., this truck had a few service bulletins for failed blower resistor. That affects everything except high speed. I realize you do not have high blower now but in any case, a bad resistor can in fact affect high blower as well. It will not be a fuse etc, its going to be one of 2 things, Either resistor has completley failed OR the blower motor AND resistor have failed.I have seen one affect the other. Step one? get up under passenger dash. have a small hammer in hand. Turn key ON. set blower on HIGH, start hitting kind of hard on the blower, Many times they get stuck and will start working again. If so? then blower is sticking and you need blower and resistor. If still will not work after hitting on bottom of blower as described? then get a resistor and start with that, If it starts again? all is good, if not? then buy a blower motor as well. Not too hard to change at all. I suspect just resistsor but.. can be a combo of BOTH blower and resistor since resistor failed a good bit back, Hard to explain all this but follow what I wrote and then start with resistor as we know that part 100% failed. I have attached a file showing locations

Thanks Hitting the blower motor did get the high to run. I will change out resistor, and pull and clean blower to start. Thanks for getting me started.

yup, figured. the bad resistor affected the blower at some point so, .. you may? need a new blower but for sure resistor.If blower continues to stop? will need blower as well
