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.

2004 Mitsubishi Lancer Problems
A hard or no start condition with fault codes P0335 and/or P0340 stored in the powertrain control module (PCM) may be due to abnormal wear of the camshaft position sensor support. Our technicians tell us a revised sensor support is available to correct this issue.
The Check Engine Light may illuminate with a stored code P0181. Our technicians tell us the fuel level sensor may be at fault requiring replacement.
The crankshaft position sensor may fail causing a stalling can/or no start condition. Replacing the faulty crankshaft position sensor should correct this condition.
The Check Engine Light may illuminate with a stored code P0171. Our technicians tell us this can be a result of an engine vacuum leak at one or more of the fuel injector insulators. Improved insulators are available to correct this concern.

2004 Mitsubishi Lancer Reviews
I love this car. I have the Ralliart and it's never been in the shop for anything other than routine maintenance in all of it's 116,000 miles. I too had the squeeking in the rearend and after put some WD40 on the trunk bushings (rubber stoppers) no more noise.
I have the 2004 Ralliart Wagon. I can't figure out why they quit making this car. It is a very reliable car. Mine has never been in the garage for anything but maintenance. I do have the problem with the temperature control knob, but am very careful not to snap it off. Love the power and the gas mileage.
I had the same problem w/ squeaking in the rear end. Had the problem fixed 2 or 3 times and gave up because they said it would just keep happening. I had the same problem w/ the temp. knob sticking, had that fixed. And I have the same problem w/ the paint. I had it buffed and waxed last year and is a totally different car now. But now I have specks of paint missing. Other than that no engine problems and the car runs like a charm! Love it! :)
I love this car (I have the sportback LS). It's got great power, is fully featured, and gets excellent gas mileage. Tons of interior room (I'm really tall), cargo space (60 ci!), and is over all a good looking, VERY FUN to drive car. Only complaint I have now is with the obnoxious squeaking rear end.
