HVAC Temperature Knob Hard to Turn on Mitsubishi Lancer

The heating, ventilation and AC (HVAC) temperature control knob may be hard to turn. Mitsubishi Motors has released a service bulletin outlining the necessary repairs. Repairs involve installing a new air blend door lever and link, lubing the blend door track, and installing a filter on top of the blower motor housing to prevent entry of dirt and debris. If the temperature control assembly has been damaged it will require replacement also.

I bought the vehicle used and the knob broke on me. The temp knob has broken and I have to us pliars to move it and I still cannot get it to go to the far side on the heater. The second knob is just stuck on the front air vent and I can't move it to the floor or the dash. I have talked to two other 03 lancer es owners with the same problem. Why can't Mitsubishi fix this instead. This problem is clearly from their end .
same issue, heater knob shaft is broken off. Been to cheap to fix it. Mitsubishi should have issued a recall for this
SOLVED! just bought the whole kit off Ebay, search for "2003-2007 GENUINE MITSUBISHI LANCER HEATER AIR CONTROL LINK REPAIR COMPLETE KIT"
The temperature control knob shaft broke because the door to operate the temperature gets stuck. We ordered the parts from the dealer and got all the wrong stuff. Looking into how to repair. Need Help
Knob is broken off and temperature must be adjusted by reaching under the steering column and sliding the plastic piece manually
I bough brand new lancer on 2003, after two years my wife was complain temperature knob was hard to turn. I took it to dealership in winnipeg, they said nothing wrong with it. They just spray wd44 on it, but wd44 build up more dirts. As I tried to change temperature the knob broke off, warrentee is over and dealer wanted $600.00. Plus amount other problems that I had complain before the warrentee it over. But deal consistanly brush off denied the problems. Original from Winnipeg Mitsubishi dealer, so I such up and move on. But I urge people that I knew not to buy Mitsubishi.
SOLVED! Heater control knob became hard to operate. Wife broke knob and then used needle nosed pliers to change temp setting, effectively destroying the white shaft. The whole control box is EXPENSIVE, but I found some replacement shafts on Ebay for a fraction of the price and it worked great! I did replace the gear kit and cable to make it work more smooth before replacing the shaft. Search for "02-02 Lancer Heater Control Panel Switch Knob Shaft". Hope it helps someone out!
I've had this problem since I bought the car off the lot with 6 miles on it. Now it will not turn at all.
The temperature knob tends to get stuck if I don't move it around occasionally, so to keep it from getting stuck I have to move it back and forth everyday.
All the knobs for the airconditioning have cracked because it was too hard to turn. The white parts are still there but cannot do anything with them without a tool .
AC/Heat knob finally broke off
Knob broke like everyone else! Can't believe Mitsubishi doesn't have parts for this, I refused to pay $500 to have this fixed. I used pliers for a while then found and bought a diy on Ebay. DO NOT buy the grey or white HARDEND CORE ones, they break!!! Plastic stripped right off the metal. I had it professionally installed and after only one day it broke and I am out the installation charges. I refuse to install another "lifetime warranty" part that is just going to snap again and leave me paying to have it installed. Instead I bought a shaft from here: http://www.blackmountaindesigns.com/shaft.html and it has fixed my problem! Here is a video how to do it: https://www.youtube.com/watch?v=R_97Y_vnPYg I don't know why we have to buy these parts ourselves when Mitsubishi should have fixed this a long time ago!!!
stuck on warm = no a/c can force the knob to a/c but doesn't cool. doesn't move easily to highest heat either
Knob was super hard to turn, ended up cracking, and eventually fell off and couldn't be put back on. So I'm currently in the winter and unable to use my heater on my car. Only air conditioner.
Currently at 100000+ miles. I just dealt with it for many years till the temperature knob broke this morning.
I have been living with this problem for 6 winters. This year it ends.
The heater knob stick really bad went to turn it an it broke
Cold Hot controller sticks and is hard to turn. Fixed it at about 120000. Looks like it is gummed up again.
Temp knob not turning, must reach under dash and move white plastic gear manually.
