Chrysler Repair: 1997 Chrysler LHS: blower motor malfunction, automatic temperature control, 1997 chrysler lhs

Question
I have power to my heater motor and it runs when I test it on
it's own. There is power to where the heater motor plugs in
but the heater won't kick in.  What could be the cause and how
do you fix it?

Answer
Hi Kirk,
There are two types of control panels (conventional and automatic temperature control) so the blower speed controls are different. You didn't mention which kind you have.
In the conventional unit there is a 'resistor block' where the blower plugs in and if that fails then you loose all the speeds other than than highest.
On the automatic temp unit the device is called a 'power module' and usually when that electronic device fails it won't turn off but I can imagine it not running at all.
In either situation, if you are getting power to the block or the module but something is wrong with the 'action' you need to replace the block or the module, particularly because you have tested the blower proper and it does work. The block/module is held in the air duct where you found the plug. by 2 screws. Remove those screws and the block/module will drop out.
If you want to tell me specifically about the situation and wire colors feel free to do so.
