Bad fuse (open), bad switch or bad blower motor.
I just had this happen to me!!! It worked just fine a day ago, now it completely stopped working.
If the blower works on slower speeds only I would suspect the high speed blower motor relay (under the hood in the power distribution box) or the switch itself. The blower speed resistor is working if all the slower speeds work.
fuse or relay most likely
either the control head is bad or there is a blower motor resistor that is bad.
If you only have high speed I would blame the blower speed resister. If you have no speeds and the fuse is good, I would blame the blower motor or the switch.
Education will not be as important as getting the opportunity to begin work as a glass blower and then take classes pertaining to the glass blowing occupation over time,
u need a new blower
Probably the blower subwire is melted and burned can be replaced 16$ from the dealer. First check the Fuse for the Blower circuit.
When you find out let me know I have same problem replaced blower fan and resisitor did not work. I have a blazer zr2 2002
Check your radiator fan switch and your fan switch coolant sensor .
Blower motor control relay under dash behind blower motor is bad or has water in it from cabin filter port.
NO. You need a VORTEC engine from the year 1997 to 1999
Could be,Blown fuse,Bad blower motor,Bad blower motor switch,Bad blower motor speed resistor,
Either the switch or resister network has failed and needs to be replaced.
did your heater switch go out all of a sudden or did some work like high work and low not work? if some worked your blower resister is most likely bad under your glove box
They told me 500$ when I went but you can do it yourself with atleast 6 hours of work
Check the 30 amp Blower fuse. If not that check the fan relay, if not that check the blower motor directly from a jump on the fan itself.
yes but you wont like doing the work
