I am confused. The fan on my grand voyager isn't working properly. I thought it was the switch, but got a new one and it is the same as it was before. Can anyone tell me why the blower only works on high?
Earlier this summer I noticed that it only worked on High, when I ordered a new/used switch it started working normally. then this morning it went out again and only works on high. I plugged the new one in and it also only works on high. Which lead me to believe that its not the switch.
(I am a quick one arent I )
It aint that cold yet, but I'd like to have it fixed before it gets cold and I know it will. I probably cant fix it myself but I know someone who can if you could point me/us in the right direction.
I would check the blower resistor and blower relay. High applies full battery voltage to the motor, while all other speeds are routed through the switch, resistor assembly and relay. When checking for voltages or wire continuity do not insert your round pointed meter lead or test light into any female socket. This will spread the terminals and cause further problems down the road. Instead, make up test leads, male on one side and female on the other to check wiring. If back probing a connector, take care not to damage the wire insulation as this will corrode and give you a wire capable of carrying voltage, but not current.
I believe you can go to Auto Zone and get a wiring diagram for the circuit.
Just go to the parts store (or might have to go to dealer) and buy a blower resistor. Then with that in hand, crawl up under the dash and find the thing that looks the same (probably attached to the blower housing), and replace it.
My prism did the same thing, and that was the easy fix.
