To clarify, the compressor and fan will run in defrost mode. The compressor and fan runs to dry out the air blowing onto the windshield.
Now if the condenser fan runs in "heat" you may have a problem with the fan relay or the main controller.

SOURCE: Dodge Ram 1500...heater is blowing cold air, even

Take a flashlight and look up under dash from center console area, across to passenger side, for wiring harness, and/or hoses(small rubber) , they should lead you to it. Haven't had my head under one of those recently, and having a problem tracking you down a diagram for some reason, but it has to be there.

SOURCE: air only blows on defrost (windshield)

Check vacuum lines on firewall for leak, check all vacuum lines if one on fire wall is ok , doors work off vacuum

SOURCE: problem with hid on 2008 dodge ram 2500

Not too much amperage. HID lights use less amps. Duh. The circuit is showing a failure in the HID kit from not enough amps so it turns off. You need to add a resistor.

SOURCE: no heat to cab in 96 dodge ram, will defrost.

you might have a vacuum leak, ck the vacuum line to the firewall where the a/c lines are at and make sure a check valve is in it also.

We have a 2008 Dodge Grand Caravan. My question is: when the engine is running, does the radiator fan run constantly or intermittently?

electric fans start to operate when the coolant temp reaches around 88 c and will run continuously while the coolant is above that temp
if you have ac then there is a fan that cools the condenser in front of the radiator and that will cycle according to the ac compressor cycles

Ac condenser fan starts running as i start engine

If the control panel is in a/c or defrost mode then this is a normal condition. If the control panel is off then the condenser fan relay may be bad and the contacts are stuck on.

2006 dodge ram 1500 condenser fan not working. Where is the A C Condenser Fan fuse located?

No one here seems to have answering the initial question, "Where is the fuse/relay for the condenser fan on a 2006 Dodge Ram 1500?"
In this year make/model, there are no "big" fuses or relays. It's all solid state and run from the (brain) main computer of the truck.
SO....if the condenser fan is not running (and the truck and AC unit are), the problem is with the fan. Turn the truck off, unplug the fan motor, and get to work on that replacement. Your safety and your truck's safety is up to you. I'm not going to go into all that CYA to keep you or me from being sued. I hope this has answered your question.
By the way, I'm having the same problem. It is (in fact) the fan. And, I'm going to replace it without disconnecting the AC lines by altering the fan shroud with my Dremel tool. What a cheap shot designing it that way...
Rock on, my fellow Dodge Ram 1500 owner!

My ac in my dodge truck only works when I am driving, but when I come to a stop it will stop blowing?

Stop blowing cool or stop blowing anr air through the vents??? If it stops blowing cool air, check if the condenser fan is running (it should be)( on drivers side under hood, looks like a small radiator) if not take a water hose and deluge the condenser with water, if it then cools, you will need a new condenser fan assembly.

1995 Dodge diesel. Heater fan runs but no air flow. Vacuum okay

Two actuators can be accessed (enough to move them) without removing it. One is on the bottom of the HVAC unit on top of the trands hump, you will probably have to remove the airbag module and cover to get to it. The other one is on the driver's side of the HVAC unit about half way up. Remove the driver's side knee bolster and you should be able to see it.
