Defrost will not blow on window and some times when I turn the heat up or down it wont get cold or hot

SOURCE: 2003 Lancer AC knob wont switch all the way over to heat...

this is due to the cable behind the dash kinking when you move the knob at worst you may need a new cable at best you can try to get your head under the dash and reposition the cable eg. cable tie it over to one side so it dosn't kink

its not to hard to do just a little hard to get to good luck

Sounds like either the a/c relay is bad or a/c compressor clutch is not disengaging. Look on the compressor for an electrical connector, and if you can, unplug it. That should stop the battery drain. I would suggest taking the car into a good a/c shop to have the compressor looked at. The clutch can be replaced without having to buy a new compressor.

1. so the knob is either broken or stiff to move and plyers wont turn all the the way to throw heat or cold air out for you.
2. gently undo the two screws underneath your heater controls ( 2 screws)
3. after that pull that peice out (there are no clips so it should be easy)
4. after that is out you have more room to play with (getting your hand up behind the controls)
5. now take the peice around the heater knobs and cd player off there are a few clips on this part so be careful not to break any but if gentle should come out easy.
6. after thats off unscrew the cd player and unconnect the attena wire (small black wire hooked at far left of cd player) and the other radio harness.
7. after that remove cd player out of the way.
8. then you can see that your heater/ ac knob switch is controlled by a plastic arm try and push all the way to the left for heat and right for cold air. (this is one of the ways if they plyers arent working anymore)
9. another place to look if your not getting the right results yet is underneath near the gas a break pedal to the right its a white plastic peice with another arm system in which you can either push toward the front of the car for heat or back to driver for cold air (may have them mixed up but either or should give results)
10. re assembe and your good to go rather then a costly trip to the dealership if your just looking to stay warm in the winter or cool in the summer.

2003 Mitsubishi Montero Limited. 97k miles. Temp gauge is erratic when actual temp is normal. How do I fix this?

SOURCE: Lancer ES 2003 Hot/Cold knob won't turn.

You have a broken mounting at the end of the cable,at the housing thats why the temp. control knob doesnt work,you can remove the center console to gain access to pivot the broken piece manually and try to modify it so you can attach the cablr
