2010 Chrysler sebring the heater isn't working. Changed the blower motor resistor and that didn't solve the problem. Took out the blower motor and checked it and it is working. I removed the insturment pannel and checked with a light tester for power to and from the switch and all seems good. Still the blower is not coming on and blowing heat. Lost on what to do please help.

Bad connection at heater box under to hood

check for relays or in line fuse in your wireing

sounds like a blower resistor. usually it is on the passenger side under dash near blower motor and hvac box. the resistor add resistance to the circuit to slow the blower motor, if it is inop then you only get high speed.

As for the a/c heater blower, I just changed the resistor and it is fixed. But, I had one speed working going in. If none of your speeds work it might be the blower itself. How to find that out is with electrical voltage meters. If your decide to change the resistor, it is behind the glovebox by the blower. Unplug the electrical plug-in and remove the 2 bolts holding the resistor in. Reverse for install. Got my resistor at a junkyard for 15. New one about 25>. For a shop to do it...lucky to get out for 150. Good luck.

Remove the lower right silencer panel. Remove the electrical connector, it is plugged into the resistor. Then replace the resistor. Since the blower motor works on high speed it is most likely the resistor.

CHECK FOR VOLTAGE AT HEATER BLOWER MOTOR IF NOT YOU COULD HAVE A FAULTY BLOWER MOTOR RELAY.IF YOU HAVE VOLTAGE AT BLOWER MOTOR THEN BLOWER MOTOR FAULTY.

If the heater fan only runs turned on full, it's likely the resistor pack that controls the speed. They usually can't be bought or put in my normal folks.

Sounds like it in the switch or the electrical plug at the switch.The electrical plug could be burnt and need repairing or replacing. Need to remove the dash fascia, Careful not to damage clips. If the cover has no visible screws or bolts, then it clips into place. Unbolt heater controls and pull contol forward. Not a fun job but with patience you should be ok.

usually when the blower motor gets old its starts to draw more current to run. which can pop fuses, burn out resistors and melt wires. also when you go to replace the resistor check the connector for signs of melting or burning you may end up having to replace that conector

You need to replace the blower motor resistor...
