TSB 05-55-003 Heater Temp Dial Hard To Turn

[jrelyea828]

Alright. So instead of making a new thread. My ac works great, but when i turn my knob from cold to hot, for one, the knob'll fling back about 90 degrees. I've tried all sorts of ways to get it to switch, but my heat will not turn on. I changed my thermostat thinking that was the problem, and noticed the heater knob acting funny. As well as that, its clear that the vent is not moving from cold to hot because you cant hear it like i used to be able to. Is this pretty much in the same category as the TSB 05-55-003?

think you could shoot me a PM with price shipped to 21849

I've had this problem, got it "fixed" and low and behold its back. I'm going to do it this time.

thanks, nice post.

Seems like it would take longer than 5 minutes! So are you saying you can just pop off the gears and put new ones on without doing anything eles listed in the TSB?

The part about discharging my AC system makes me not want to do this. But my temp dial can be a PITA, esp when passengers try to adjust it and don't know how to do it right since it binds

I too would like to know this as I've been living with this problem for quite some time now. Luckily I live in an area where it doesn't really get too cold.

Exactly what I'm saying. By replacing the gears you change the fulcrum point of the linkage therefor alleviating the binding problem.

Ok, I just did this on my 2003 Evo 8 and it's definitely possible to change the gears just by climbing underneath your steering wheel column.

Be warned though, it requires a fair amount of being nimble, agile & patience.

I had to squeeze myself under my steering wheel UPSIDE DOWN. Make sure you get a short (length-wise) Philips screwdriver cause if not regular length ones will hit on your steering wheel column.

But other than that, it's possible.

UNFORTUNATELY, that didn't fix my problem. My problem it turns out, is the cable that pushes & pulls the gears forwards & backwards, which is connected to the heater control knob itself.

I guess over the years & usage, the cable itself has become "loose" so to speak, whereas it should be taut.

So what happens is when you turn the heater knob one way (say to max A/C) & want to turn it back to max heat, the cable flexes and refuses to push the gears back into position fully.

I believe my next step now is to replace my cable itself

my a/c knob has been broken for quite a while i posted a thread in lancer forums and someone directed me here. Im new to all of this so i have no idea how to fix it. i been told to find the part at a junk yard but i cannot install it...

I never knew there was a TSB on this. I just called DOn herring plano mitsubishi and they quoted me 2500 for the job. I was never notified there was a TSB.
