The blower motor in my Skylark has not worked in nearly 15 years. I always thought it was the blower motor. I replaced it a while back and it still doesn't work. Before it went out I recall it always blowing and wouldn't change speeds. The fan switch on the dash feels loose. Do you think it's the switch or the relay? Is the relay on the center of the firewall the one for the blower motor? Does the blower motor need to be grounded? I only recall one wire plugging into the motor. Thanks for any input.
