The Heater and A/C blower fan will not turn off

I have a duel control heater and A/C. While driving in cold Mountain Terran, the heater starts putting off only cold air. However, after pulling off at a gas station and letting the car idle in park, it put off heat again. Upon arriving home everything seemed to go back to normal, until today. Now, when I try to turn off the heater a high blower turns on. Not sure if the A/C works, it's too cold outside to tell. The blower appears to be like the recirculation fan. Can you tell me what this fan or blower is and how the heater can be turned off?

SOURCE: 2002 caravan, heater problems

That was a common complaint a few years back, due to the fact that the heater core is a little too much higher than the engine, which requires that extra push it gets when engine RPM's increase. One thing I did do on my Caravan was remove my hoses to the heater core, and use a small external pump with hoses to circulate C.L.R. through my core for a while, then let it sit with CLR in the core overnight.Next day I circulated it through again, both ways by reversing hoses, and then re-attached hoses, bled air out of system, and notice quite an improvement in heat at idle. Once cleaned out, the heater core allowed coolant flow through it better at idle. If your stumped by explanation, take it to an automotive shop, or a Rad shop, and get a quote on flushing that core out for you. I recommend the CLR, but it might be too time consuming for you , but a flush will probably show some noticeable improvement.

SOURCE: heater control only works on high

You need a blower motor resistor,and the heater blower motor should be checked for high amp draw. check Napa for the part or go to Dodge..prpbably about 60.00 dollars.

Blower control


Sounds like a thermostat and/ or the system is low on coolant.
Its probably not going to reach 200 degrees when the outside air temp is below freezing, but you should get plenty of heat if the system is working correctly.

Rear blower: only works on high when set on cold, won't work at all when set to heat


I would start with the rear blower motor resistor, the resistor is what controls the speed of the fan, the resistor is located in the rear heater box near the blower, you will need to remove the right rear side panel to access the heater box. start with that

Why wont my a/c or heater fan come on?


When the blower works only on the high setting its usually a bad blower resistor which is right near the blower motor. now you say it would always blow high regardless of the fan speed setting that would indicate probably the climate control unit or a connector problem somewhere. finally it not working at all may be the climate control unit or connection went bad even further. it might have a blown fuse or a bad blower motor in addition to the climate control unit or connector problem .check for power and ground at the blower motor. the power is supplied from fuses and may have a relay also. the ground is supplied from the climate control unit and goes through the resistor to control the fan speed. good luck

Location of blower resistor on 2003 grand marquis?


Hello, Just follow the wire from the heater fan under the hood. Trace the power wire from the heater fan and it will join a connector midway on the Firewall. It will have 2 screws and 1 electric connector. Tap the connector with a screwdriver handle and see if the part starts working again.

If it does not, get a used or new blower resistor. Work on a cold engine and remove the screws and connector from the part. Temporarily plug in the new part to the connector and turn the Key to run with the fan ON. It should be blowing now. Turn off the switch and put the new part where you can reach it with 1 hand.

Undo a heater hose at the top rear of the motor going in front of the opening for the switch. With 1 hand remove the hose end, then switch parts with the new blower resistor with the other hand and slide the heater hose back on its fitting. Tighten the heater hose.

Then secure the new part into the Firewall and fasten its connector. You should have lost little Antifreeze by working on a cold engine as the hydraulic lock kept the fluid from running out.

This should be all you need to do except clean any spills away.

2004 silverado for some reason the heater/ac control only works on the 5 setting and when the heat is on only blows out hot air on the passenger side and cold on the drivers. i have replaced the blower...


Well had the same issue on my duel climate controll 04 2500HD but changing the heater control solved the different temp.The only other thing would be your mixer door motor.There are two,one for DR side is probibly stuck..As far as the blower motor.The resister should have taken care of that.Sounds like you may have another bad one.May want to take a volt meter to the resister plug in and run you different fan speed just to make sure that you get voltage to the different conecters.

Heater fan blowing intermittently or not at all


Most likely it does, if you can hit the motor and it will run. I can't say for sure but you might want to chk. to see if you got a heater blower motor resister. There located (if its got one) around the heater motor and it controls blower speeds, might be worth checking out.
