Power coming through but selector switch not working
Power is coming through but selector switch is not working.
It has had periods of being very stiff to turn but now it is loose but is not working. I don't know what to do but would prefer not to call in a repair man as I am pensioner.
I should be grateful for any help anyone can give me!

Not sure what a common relay terminal is.
The blower relay gets power from a 50amp fuse. Power goes to the blower motor and the resistor and speed switch provide the ground circuit. The on signal for the blower relay comes from the selector switch.
The red-blue wire is a direct link between the relay and the lights, there is nothing between the two components. Is there power coming out of the relay for that wire ? The b/w wire is power from the same fuse the shift selector switch is powered from. The red is power from the shift selector and the w/r is ground from the computer.
I'm willing to bet that the heater is grounded. Probably burnt up the original switch, heater wasn't getting power, therefore not tripping the breaker. Now the switch works, heater gets power and immediately trips breaker. Unhook the switch and tape the wires, reset breaker and try in heat and cool. If no problems it's likely the heater.
if you can check by an electrical tester then first open control panel and check electric(main electric ) supply is reaching till the selector switch if its reaching supply the try to turn your selector switch on fan mode and check the connecting point of selector switch electric supply is now come on fan supply point ( where motor wire is connected that point ) if its working like this then its mean selector switch is ok and problem in fan motor , its need to replace .
if you how know to read a electric tester then check you air con,s selector switch please find out the fan motor wire in selector switch and test one by one and turn to fan on high speed mode and check on selector switch there electric supply comes on selector switch if it,s come and motor doesn't work then it,s mean motor high speed is defective if supply not come on selector switch then it,s mean selector swith is faulty .
if you can check like this then do if not then contact to a technician,
it could be a weak fuse, the selector switch can be failing, the wiring could be faulty, or the motor itself might be going out. turn the selector switch on and if they don't come on, remove the connection from the motor while the switch is still on and connect a multimeter, if you have power than its most likely the motor, if no power change the fuse and if still nothing it probably the selector switch. I hope this helps please rate this thank you
I would start with making sure ur selector switch is not in the off postion just in case lol. next I would have to take door panel off get at the switch and see if you have power going to the switch this can be done with just a 12volt tester. Then if power is coming to switch operate see if power is going out, use selector switch to see if power goes out to left then try right mirror and for fun in off postion no power to either. the switch may just have a bad connection or broken because it is very douhtful both are bad but if the mirrors never get move they can seize up it a good pratice to more them every so often hope this helps get started in the right direction.
unplug the power to the system completely.
Locate the mains voltage selector switch and toggle it from 110 to 220 and back a fiew times. BE SURE ITS SET BACK!
This has been known to reset a power supply that is in SHOCK.
If this does not work or you cannot find the red selector switch. then leave it unplugged for a while and check that there is nothing shorting the power supply.
Also let me know if it is able to DO ANYTHING like lights or if it looks to be trying to start and where it dies.
