    Cool Solution To Flickering Fan Speed 2 Or 3 A/C PART 2

    OK, so last year I found a solution to the flickering A/C light on certain fan speeds that worked for me and many others.

    http://www.mazdas247.com/forum/showt...hp?t=123678787

    Basically, squeezing the contacts of the wires going to the fan speed with pliers solved my problem...for a while. The solution could last weeks, maybe months, then return. Well my problem came back this summer and taking 10 minutes to remove the bezel and squeeze the contacts worked...but then I decided to go all the way. I took everything apart and SOLDERED the wires to the fan switch. Now, I don't have ANY problems at all. I used to still get a slight flicker of the A/C light if I slowly turned the fan position switch between 2 and 3. This no longer occurs. The A/C light stays absolutely SOLID the moment the fan switch leaves position 0. I'm gonna post pics tonight or tomorrow. Hope this helps someone. Be cool....

    EDIT:

    OK, I just added the pics...
    FIRST, make sure your key isn't in the ignition!!!
    1) the switch
    2) I cut the black housing to expose the male contacts
    3) Plug-in the wires
    4) Solder the wires. Make sure you heat the contacts properly (ESPECIALLY the male) or the solder won't stick properly! Use flux, it helps. This is very important.
    5) Hot-glue the S**t out of the entire contacts. Let cool, then glue again. Make sure there aren't any contacts exposed.
    6) shown below...wrap in electrical tape for good measure

    i purchased a new switch from the dealer last year. didn't help. I don't know if the metal clips on the wires are too soft and come loose with vibration and temperature changes (expansion/contraction) or if the spacing of the male pins to the female plugs differ that causes them to lose contact with each other. In any case, I suggest cleaning the contacts and squeezing with pliers first.

    What about a bit of dielectric grease on the contacts.. that might promote longer contact life...

    Umm.. Dielectric grease is an insulator not a conductor

    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...

    Melted Wires...

    When I went to clean my connections, I found that my female plug had been melted in two of the thick wires, I am currently working on replacing them...
    Don't know how this happened but I'm sure it was part of the control problem.
    Any replies to how this could have happened
    Also sorry for the poor pic quality, my regular digi cam is on the fritz...

    I thought about the dielectric grease too but from all the crazy things I read in that last A/C thread, it sounds like it would only be a quick fix and problem would come back.

    Interested in the soldering idea though as I've been ignoring my A/C problem for a couple years now. Summers are getting hotter though! Subscribing...

    So far...it's been working for 2 days. yup, a FULL 2 days.... hehehe. Tonight, the slight flicker between position 2 and 3 came back a couple of times. But the A/C light has not flickered at all during any position....

    Do you just remove the fan speed cover, the connector and pull the switch out?
    It starts doing this now, and it's really annoying. I will definitely try plier squeezing!!

    Thanks

    1) Remove the 3 knob selector switches by gently prying them off with a small flat-head screwdriver
    2) You can reach-in to where the knobs were and pull-out the bezel
    3) You can pull-out the top part of the bezel by sticking your fingers into where the vents are. Un-clip the wire harness for the hazard lights
    4) You SHOULD un-clip the 2 cables that control the temperature and vent positions
    5) You can un-clip the the wire harness at this point
    6) if just squeezing with pliers, remove each wire individually from the harness and squeeze with pliers.
    OTHERWISE...
    7) you will need to remove the box that contains the switch from the bezel by un-screwing 4 screws. 1 on each side, 2 on the bottom if memory serves.
    8) un-screw the 2 screws that hold the orange faceplate
    9) un-screw the white plastic nut that holds the switch in place

    Hope this helps....

    I would expect a flicker between positions, just not when it's in a NUMBERED position. Thanks for the thread!
