The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

blower stopped working and intermittenly works at a very low speed. Resistor pack was not the problem. We are still trying to figure out what is wrong.
Same..the blower only works on high. Good heat, just can't reduce. My daughter is hard of hearing, and it makes it difficult when she can't turn it down to hear a conversation. Very annoying!
The first two speeds quit working on the blower so I only have the upper speeds, which sometimes are to high for my newborn.
only works on high, if you leave it on anything but off or high you can hear a weird noise every couple seconds like something is trying to work. not fixed yet.
It started making a funny noise when running AC/Heat. Then finally the 3 lowest settings stopped working all together. Only the 2 highest settings remain working. If I could figure out where the switch is at, I would test it to fix the problem!
The first two speeds of the AC are not functioning. It's either a full blast or air in my face or nothing at all.
i will turn ac on and the blower will kick off for a while or until i shut the car off and start it again. this just started yesterday.
