Solution To Flickering Fan Speed 2 or 3 A/C

I finally found a solution to MY A/C flickering on position 2 and 3 problem. Canadian dealer wanted $420CND + taxes. US dealer would be around $190US.

PROBLEM: A/C light flickers on position 2 and 3
PREVIOUSLY TRIED: Replacing switch, cleaning all contacts
RESULT: Worked for a day or 2....

SOLUTION: 1) Pull out each wire (1 by 1 so there's no color mix-up) using a tiny screwdriver to lift the tiny tab inside each wire housing.
2) Clean each contact with isopropyl alcohol or similar
3) Squeeze the connector closed with pliers
4) Re-install


Before doing this, I noticed that if I would pull the wire harness out a couple of mm, I would lose electrical contact completely (obviously). But what surprised me was that when I would push the connector in SLOWLY to the point of just making electrical contact, only fan speeds 1 and 4 would work. I would have to push the connector in further to engage all fan speeds. After squeezing my contacts, I now have the A/C light completely solid during ALL fan speeds, EVEN when I pull the connector out a few mm. So this worked for me!

Try it and post your results!! Put a STICKY too!!

EDIT: I JUST ADDED A PIC WITH THE PINOUT SHOWING WHICH WIRE CONTROLS WHICH SPEED... THIS MAY HELP YOU ISOLATE THE PROBLEM WIRE...

These are found behind the climate control panel. You have to pull off the front bezel, detach some wires and 2 cables found under the dash.

Mine only works on position 4. Even then I have to fiddle with it to get the damn thing to work!

Does the fan work from 1-3? Or is it just the A/C light that stays off from 1-3? I know the resistor pack is responsible for the different fan speeds, but not sure if it ties in with the A/C compressor. Doubt it...

The light goes on for all 4. However no air comes out of 1, 2 or 3.

Thanks for the How-To, ask the mods to move it. I replaced my whole circuitboard trying to fix this, and no dice. Now I'll do this one! :D
