Now I know what your thinking its the blower motor, but I changed that out and yes the screaming has stopped and I have a ton of air coming through the vents on high only. but all other settings it just shuts down. HELP please. I looked for the relay if there is one and was unable to find it. Thank you in advance for any help you be able to give.
Hello and good day:
Have you checked the Blower Switch?? I would suggest that you inspect/replace the blower motor resistor . The blower motor resistor is used with the blower motor switch to obtain the different fan speeds. If this resistor is bad, some speeds will work while others will not.
The Resistor is located Pass side under dash. remove the cover, and look for a bunch of wires going to the resistor card which is screwed into the evap/heater box
I have heard of this before....I will P/M some of the Guys (Tbird, Chipset, 360ci) and see what they can say.
