Hi everyone, I replaced my blower motor regulator and have a question. As before the regulator was replaced my fan speed never slows down the display always shows 3 or 4 bars. Is this normal? Should the fan slow down to 1 or 2 bars depending on temp if set to auto? I can manually lower the fan speed to 1 bar or 2, but if I hit auto it jumps right back up. It might be the way its suppose to work, but just wanted to be sure. BTW, I did a search but could not find the answer

TIA

I noticed that when in Auto mode the fan speed is in the center (3 - 4 bars) once the interior temp has stabilized no matter if the Air conditioner is on or the Heater is on.

Ray,

Thanks for the reply. Sounds like mine is working as it should. I thought it was, but just wanted some confirmation. Have a great Holiday
