Chrysler Repair: Blower Motor - 99 Sebring, fuse box, blower motor

Question
My friend has a Sebring convertible.  She has told me she only gets heat when she is driving faster (over 40mph).  I think she told me the fan just stopped.

All the fuses are good and connections seem secure.

I think it is the blower motor.
Does anyone have instructions how to check if this is a good guess?

I don't have a manual for this car but any blower motors I have replaced were not fun.  Anyone have illustrations of the process?  

Answer
Hi Bob,
There are several possibilities. First I would check to verify whether the blower is working or not by listening for when it is turned to all the speed positions when the ignition switch is in the run position. It is located under the dash on the far right side, behind the glove box. If it is not working at all then I would check fuses #11 and 13 in the fuse box under the dash immediately next to the driver door opening. Look at the wire in each carefully to make sure that it doesn't have a subtle crack or even better check it with an ohmmeter for continuity (0 ohms). Then if that is o.k. I would look immediately above the fuse box where you will see two relays, side by side, and the one to the right should click when you turn the blower motor from off to low which if it doesn't would make me suspect that blower motor relay is bad. If it does click then see if the blower operates on low, med, med hi, or hi. If it doesn't operate on any of those then I would suspect the motor is bad. But if it operates on any of them then I would suspect the "resistor block" near the blower motor if only the hi works, or if only hi doesn't work I would suspect the hi speed relay near the blower motor. To get to the blower motor area it appears that all you need to do is remove a stop on the left side of the glove box lid which allow it drop down further and get behind the box for access to the motor, resistor block and hi relay, but let me know what you find before I give you more details on how to get there to service any of those three items. I need to study the diagrams a little more...
