We have a motorized MCD shade on our windshield. Privacy shade works fine. Sunshade quit going up or down after beeping 4 times and now doesn’t beep either. MCD said check voltage and to see if you have current at the shade too. So we have a multimeter but don’t really know how to check this. I pulled the toggle switch up from the dash and it is just a mass of wires that appear fine. I hate to order a new motor if it’s just a connection. I’d appreciate any help. Remember this is electronics for dummies!
