Heater blower problems
I have a 98 chevy pickup. The blower motor quit last week, so I replaced it. When I removed it, I noticed ice in the compartment the fan slides into and on the fan. I cleaned and dried it all up and installed a new motor. My questions are this...1) How in the world did I get ice/water in the blower fan compartment? 2) When I tested the new blower out, only the high setting works. 1, 2 and 3 have nothing, 4 works great. What would be your guess on whats wrong?
