Thread: blower motor not working on 5, but works on 1-4

When I turn my AC and heat on, it only works on 1-4, 5 doesnt work. I read online that if the blower motor resistor fails, 5 should still work. So im having the opposite issue. I checked some fuses in the glove box, anything with HVAC or AC and they all seemed fine, so i'm not sure whats going on. Any ideas?

A little dinkin around ..buy one from Oreillys, if it works great if it doesn't return it.

High speed has a relay for direct power. And its own fuse.

I'm always learning here.
and I'll forget by tomorrow

I have the same issue in an 03 GTP. Have not looked at anything yet.

So if the fuse seems fine, the relay then? also, do you know what exact fuse is for the high speed relay?

edit: i think i just realized, the relays are in the fuse box?

Looks like I would check the HVAC hi fuse in the glove box.

My fuse was ok. What relay is it? Can't really tell from the book.

For future reference, on my 2001 SE, the high speed relay in built into the blower motor resistor.
I only had 3 and 4.
No 1 and 2, and no 5.
Blower motor resistor fixed it, have all 5 speeds now.

The high speed relay is usually part of the blower resistor.
