2000 focus blower issues

[kimszoo]

Lately my blower motor only works on settings 2&3 usually, though when it's cold outside it sometimes works on 2,3 &4 or just 2&4. Now it also no longer works on defrost, bad time of year for that here, but works on other settings. I originally thought it was the resistor pack, but now I'm wondering if the blower motor is weak as well. Am I on the right track?

I would check the switch and wiring connections. If it was the motor, chances are it would act up on all 4 speeds, and the resistor pack would only affect the three lower speeds and is bypassed when in high. Hope this helps. Good Luck.

The lowest speed IS generally the first to go when it's a resistor pack issue, but once one of the resistors burns out it doesn't "fix" itself - so intermittent operation points to the switch or poor connections.

Blower speed is not dependent on air distribution settings (not interconnected) so the only relationship I can see there would be possible "jiggling" of the blower switch/connections by touching a nearby switch.

"Weak" motor, or not working on lower speeds due to "drag" from leaves etc. would be indicated if it always worked on higher speeds but inconsistently on lower ones. Your note that it works on lower speeds & NOT on 4 at some times leads us back to the switch/wiring as the most likely problem.

luck!

To access the switch and wiring, do i have to rip apart the dash, or can I get to it through the radio or glove box? I've searched the how to section, with no luck

Here is a great How-to: HVAC (Climate Controls) Broken Cable. It is a little more info than you need, but shows how to get to the switches.

Thank you, that's a great how-to.
I have the trim panel off, and I'd say my vent selector switch is likely faulty..it rotates freely except for vent selection you can feel/hear it doing something. My wiring doesn't have any obvious problems and the connectors look good. The cables don't have any breaks that I can see, is there more to that?
The blower speed switch looks and feels like it should work, and of course I can't find my multi meter to test any of it. :(
My blower now works only on 1 & 2, on heat and A/C settings. On the floor it's fine, the vents it barely pumps out. Blower motor slowly dying? Or is there anything else to check without a meter? Freezing rain here and snow expected, so I'm in a bit of a panic to get it fixed

Thanks....when you move it to vent, does it continue to blow out the floor? If so, the cable is probably broken inside of the insulation. If you change the selection, and you cannot see the large black plastic moving in this area (behind where the cables attach) :



Cable is probably broken.

When I did mine, I had to change out the fan speed switch. 1-3 worked fine, 4 only worked if you pressed the switch in. I would be inclined to thing that the resistor pack is going out in your case though.

nomind again thanks! Nothing is moving where the cables attach, so at least I know what to replace
But I replaced the resistor and still have only speeds 1 & 2, guess I have a spare now :) Other than the blower itself, is there anything else worth trying?

[nomind]

Maybe the blower switch?

My blower switch was bad, didn't work on number 4. Junkyard switch and I have high again. Also my selector cable broke so I could not change the vents the air was coming out of. New cable and I'm a happy guy.
