Question about 2005 Chrysler PT Cruiser
What could be some problems and solutions for my 2005 Chrysler P T Cruiser ? When after starting engine and turning on heater motor engine will start running rough and sometimes almost stalls. It makes no difference if it is on low or to high speed. Does the same thing if A/C is on or off.
You should know that the air conditioner compressor comes on when some of the heater functions work. That happens to remove the moisture from the air in the cabin so that you don't get foggy windows. The first thing that you need to check is air conditioner compressor. See if it is coming on. Then it could be the compressor, You can unhook the electrical connection to the clutch on the compressor to see if that is the problem. If not then it could be the body control module.

I had the same problem, could not figure it out. Looked all over the inter net found a post that said something about the ground wire that had a bad connection. So i followed the found wire and this is what i found. attached photos, plus whati did to fix it.

I had a similar problem with my car. It turned out the O2 sensors were fine and the issue was a leak in the throttle body causing the engine to run lean. If you have an ODB2 scanner you can look at fuel trims, etc and will be able to tell.

SOURCE: ac fan won't turn off
In my 2001 Town and Country without automatic temperature control, my heater/AC blower suddenly worked only when set on high. Usually, that problem is your blower resistor pack.
I had to search for the one in my van since the parts man wasn’t sure where it was except that he thought it was in the dash somewhere. (In some other vans it was under the hood.) My Haynes manual didn’t have anything on it except a picture showing it with the blower. I found it directly behind the glove compartment. Very easy to get to once you know where it is.
The glove box can be lowered all the way out of the way just by pulling in the sides so the rubber stoppers come out toward you. The sides bend easily to allow that.
The glove box being out reveals the resistor in the heating duct right in front of you. Just remove the two sets of wires and two bolts (10mm socket, I think) and the resistor pack slides right out. Then bolt in the new one an plug the wires back in (they only fit in one way). Fold the glove box back up and press the stops in to get them back in place and you are done.
The resistor pack only cost $12 and change at my dealer. It is part number 1-04885583AB which was a replacement for the same number with AA at the end, so I’m guessing they had a lot of trouble with the AAs and so made a better AB.
Last Winter my heater blower fan worked only on High. I changed the front heater/AC blower resistor pack and was surprised at how easy it is, but I had to figure it out for myself since my Dealer's parts guy was no help as to where the part lived and my Haynes manual was just plain wrong. This was on a 2001 T+C. I'd be very surprised if the 2001 Caravan was any different. Don't know what other year vans would be the same. I do know some earlier generations had this resistor under the hood and Haynes had is with the blower sort of behind the instrument cluster.

If you are talking about the cooling fan relay for the radiator there is no low speed and high speed relay. There is only one relay and it is behind the grill revitted to the bumper rail. It is doesnt look like you typical relay.
