Question about 2003 Mitsubishi Galant

No Heat I have the same problem with mine. For a while there was a grinding sound when I turned the knob from cold to hot but the heat would still blow out and now I have no heat at all. Looking for a solution.

I would check your blower motor or your heater core. maybe even the blower motor resistor. another thing i would look at is the thermostat. alot of times the thermostat gets stuck in the open position or the closed position. in your case i would say its in the open position. a thermostat shouldnt run you more than 20 bucks as for the blower motor, heater core, or the resistor. those can be very expensive. start with the cheapest thing first. the thermostat. the location of that is going to be behind one of the hoses attacked to the motor from the radiator. it will not be the hose coming from the water pump(normally located towards the bottom of the motor) it will be the hose that connects to a housing on the motor. the house is a aluminum housing so be carefull removing and installing this piece. the thermostat will be located right behind the housing.

Hi, the flaps that direct the air for either hot or cold air works with servos situated against the heater box. The grinding noise was the gears on the inside of the servo stripping. After numerous reset processes (switching the car on and off), the servo was reset to its normal state which is in the cold direction. You will have to replace the servo in order for the heater to work again.

My heat won't get hot on my acura cl 3.2 2003. It will blow but not heat. A/C works fine. What happened?


turn the heat knob all the way to hot (highest) setting and when it starts blowing heat you can turn it down to a comfortable temperature
At least that's how mine works

2005 RX8 heater is blowing cold air. Fluids are topped up.


You need to repair the heater core with a soldering gun.

If you do not have heat, or only have heat, IMHO it is most likey the AC/heater control unit. This is the part which has the AC/heat control buttons and knobs.

Easy Diagnosis:
The easiest way to verify this is to turn on the radio, press and hold the power on/off button and press and hold the scan-up button for a second (full second). The word "A/C TEMP" should appear on the left of the display and a number from 0 to 16 on the right. I suspect yours will have the number 0 (or 16 if heating only problem) displayed no matter where you turn the temperature control knob. If this is the case you could turn the temp. knob to full heat and see if it goes to 16 after pushing down or to the right on the knob.
In a working system, the number moves evenly in increments of 1, from 0 to 16 as you turn the temperature knob.

Easy Fix:
I was able to take mine out and solder 3 loose connections to fix it.

The beginning steps are the same as for any radio removal procedure and check for loose connections.

Cold to heat knob in my ford f 150 is stuck on cold, and when you rotate it to the warm setting it will not let the heat in !


Make sure its really turning, the knobs are prone to crack, and you end up turning the knob, but not the shaft. The knob just pulls straight off, take pliers and gently turn to hot. If that works, replace the knob.

Heat


Mine did the same thing. The quick fix is to turn the knob to the heat side, then push gently on the knob itself. You'll instantly feel the air get warmer. The real fix entails taking the dash apart.
