    RESOLVED! (so far... )

    OK... so Y0sky and I took my A/C controls out. I took the fan selector switch apart in the back and dremmeled it down so I could get to the 5 connector blades. Then we popped out all 5 wires from the plug side. We then plugged them in, crimped them down, soldered them, and put it all back together.

    So far... so good... all fan speeds work with no flickering etc. SOLID.

    So no, it has nothing to do with the motor. It is strictly an issue with those connections to that switch over time. Maybe they loosen up just a bit and the two metals used are not very compatible for conductivity.

    ya, i looked at the schematics and it would seem that the culprit is in the switch itself (there's nothing going on at the motor that would casue this kind of issue) it's always sounded like a bad connection to me, but if the soldering doesn't work....?

    Only other thing I can think of would be to get a small file of sorts to file both the inside blade connections and the connections inside the plug (after you pop them out. Then crimp the female (plugs themselves) tighter so that when you put it back together the connections will be tighter and make a better connection. I bet that would work. I am guessing some metal oxidation is occurring where the metals contact each other causing a poor connection for electrical current. That would actually be a pretty easy solution and I am betting would work just fine. This way you get to keep your stock plug etc... I just wanted to solder mine since I have seen it mentioned to be successful so far and didn't want to have to take it apart for the 10th time...

    Yeah, cleaning the contacts and crimping them down was the first thing I tried last year. No idea why, but it didn't last very long. That's why I soldered it this time. 2 weeks so far. Not a single problem yet. Thanks PyroTek and the rest of you for posting your results!! I just have no clue why these contacts are such an issue. Most of the car's electrical are connected in a similar way. Now I'm worried!!

    most of the time when you have this kind of issue, it's caused by over heating, either by poor connection (meaning loose) and or, too heavy a load (amps) for the wire/spades/connectors etc...???

    Actually, I did do one thing different...

    Instead of popping that entire rotary switch out, I left it in and took it apart on the back side. It basically snaps together. Under that back cap you will see the connecting points/contacts. There is an electric grease substance on there and I cleaned some of that off, not entirely, but some of it. Not sure if anyone else took the switch apart like I did, just an extra tidbit of information.

    Nope. Lithium (dielectric) grease is to prevent corrosion on electrical connectors because it does conduct.

    I scrapped the conectors and reapplied new grease. Works today. I was too lazy to completely remove the switch...

    Me too, I just lost fan speed 4, so now I just have 1 and that won't cut it. I was looking at the board as the culprit as I have already done the pop the wire connectors out of the harness wire crimp method. I'm still not sure, it would seem that if I had a bad connection the fan just wouldn't work on those speeds, not the AC stop working. I'll try this method soon and let you all know my results.
