What is your question?
My blower mower stopped working completely, there is absolutely no action when turning on ac or heat, on any levels. It literally was working fine yesterday and stopped overnight. I'm guessing its an electrical switch, fuse, relay or motor problem but what is the best order to go in testing wise if you have no power on any speeds? Other posts I've read on here mostly had some power on a certain speed indicating the motor was still working. Thanks.

Do you have a volt/ohmmeter , to check power/ground at the blower motor connection? OR.......locate blower motor (under dash behind glove box-may have to remove small trim panel on some) , turn the fan switch on 'high' and bang the motor a couple of times......if it makes noise or actually starts working , then either the motor has a dead spot in it or you've got a poor connection. IF it does start working after you bang on it , most likely , it's worn out and should be replaced(3 screws , awkward , but not to hateful. IF nothing happens , start back with my first suggestion and get volt/ohmmeter to test. ---Checking ALL fuses first would be good too. Another hint- with switch in 'off' position in a quiet area , listen for a relay 'click' when turned on , may or may not be noticeable , but if you do hear it , that's another sign that the switch is working and the circuit is complete , to that point.
I do have a volt/ohmmeter to test it, I will try all of these suggestions and see how it goes. Thank you!
