A/C blower/fan has stopped working
My 08 F250 6.4 was bought from a private seller about a month ago with 128000 miles. I noticed to following day that the A/C made a "huffing" noise. I took the truck to the shop to have all inspections done and was told I needed an A/C Control Head. I was explained that the A/C Blower could not decide between speed 1 and speed 3 and that was making the "huffing" or blowing noise. The price was $475 parts and labor. I looked online and found a OE Blower Speed Motor Control Module #: 9L3Z-19E624-B. This part is located behind the glove box. Is this the part that I need or is the truck shop talking about a different part altogether? I don't want to spend $475 for a $100 part and 15-30 minutes of my time. I also don't want to spend $100 for a part I don't need.
