What would you like to do?
I had same problem it is the control regulator a little circuit board under the glovebox it is a plugin and i think it was a cheaper part if i remember right just unplug old one and plugin new one

Answer fuse, bulbs or switch
If it is a 2.7 litre engine and the engine temperature is normal, you probably have a low coolant level and the coolant system needs to be bled. The heater core and top …of the engine sit higher than the radiator and air bubbles are trapped there and not allowing the water to pass. At the top of the engine, just left of the intake manifold, you will see a small bleeder assembly. Place a clear hose on the tip and open the valve letting the water run back in to the radiator storage cannister until all the air bubbles have stopped passing through the hose. You may have add additional coolant and you may have to bleed the system more than one time, especially after driving the car again. If you have noticed the engine coolant temperature guage fluctuating when you are driving, that is usually a good sign the coolant level is low. The temperature sensor sits right next to the bleed valve, so if there is air trapped in the system, it shows the temperature to be low or cold.
Have you checked your coolant levels? Simply put, the heater runs by blowing past the hot coolant pipes and gives you warm air.
Answer I have had this problem too, but it was with the front heater/AC unit. It would only blow high, after about 9 months of this it just quit and now nothing comes out. I… am in the process of finding the part. Two part shops that I have contacted don't have a listing for it.
Should be located at the engine end of the upper radiator hose On the 2.7 motor the thermostat is located at the engine side of the lower radiator hose…. It's a difficult job to change, the alternator a/c compressor and bracket need to be removed, at least unbolted and moved aside, and they have to be accessed from the passenger side inner fender as well as from under the hood. If you also remove the dipstick be sure to cover the hole so anti freeze can't get into the oilpan. I just unbolted the dipstick and moved it away without pulling it out to avoid that. Upon finishing I also had a problem with air pockets in the system when refilling with anti-freeze, the system must be bled well.
The most common cause is a failed blower motor resistor.
you will need to replace the "fan blower resistor" it is about $70 for the part new, $4 bucks for one from a junkyard, it is located under the passanger side of the dash…, it has 5 or 6 wires and 2 screws to replace it...it took me 15 mins to do the job...pratice on a car in the junkyard, why screw yours up ;)
The high pressure AC switch on a 2002 Chrysler Sebring is located on the passenger side of the engine bay. It is paired with the low pressure hose and is mounted near the …coolant and power steering reservoirs.
2000 Chrysler sebring the blower fan only works on high speed Is it the resistor or the switch Does any on know where the resistor is located Thanks?
This is indicative of the blower resister failure. The resister is designed to fail "open" on the "maximum" position to permit continued operation. The resistor sho…uld be located on the passenger-side of the vehicle, accessible under the dash by removing the "soft" covering. Make sure you get the correct part to fit or you may have to modify the opening where the resistor fits for size (newer resistors are designed a little larger, requiring you to expand the opening (all plastic, so not too difficult, but it is a hard to reach area so working in the space is difficult)
The most likely answer is that the Blower Motor Resistor has failed, it's a very common problem. A dealer will charge you about $160.00 for the repair. However, it's an ea…sy fix. The new resistor card will cost between $27.00 - £50.00 depending on where you buy. I paid £29.00 at O'Rielly's Auto Parts and did the job this morning in 20 minutes. You will need an 8mm socket (a magnetic socket is preferable), a small flat bladed screwdriver a ratchet and extension, a file, a mirror, a flashlight, between 10-20 minutes and some patience. Pull back the passenger seat as far as possible. Under the dashboard in the passenger foot well you will find a molded cover. Remove it. Some are held in place by a push pin, some by a tinny cheap nut as was mine. I used a spark plug socket to remove it, because, unhelpfully, it's on a long, pointles plastic post. Use the mirror and flashlight for improved visibility if you can't squash your head and shoulders into the space, it's pretty tight. Follow the wires from the blower motor. You will see they lead to the resistor plug, held in place by two 8mm nuts. Remove them and the card will slide out. The resistor card will unclip after you use the screwdriver to remove a red plastic tab that holds the clip in place. It annoying and useless. You may have to pry the plug off using the screwdriver even after getting the tab out. The chances are that the new card will not fit into the slot, the design has been upgraded from the original part since failure was so common. Use the file to enlarge the slot, being careful to remove all debris. Replace the card - easier if you have a magnetic socket, it stops the screws from falling out as you try to get them to bite. Replace the cover, and job done. Good luck with your repair.
