1999 regal ls fan/blower problem

99 regal LS 3800 dual digital climate control, I can set ac/vent on mid vents high speed and blower automatically on its own turns off mid vents and may run at a slow speed through foot vents then turns back on high through mid vents. will run several minutes on high the nothing for a while..would I start by replacing the blower control module?

will run several minutes on high the nothing for a while..would I start by replacing the blower control module? The strange thing here is, “will run several minutes on high, then nothing for awhile”. What are you saying, that the blower shuts down, or that the blower is still running, and you just have no air flow?:screwy:

I set the blower on high; flow is set on mid vents then automatically it shuts off the mid vents and blower runs low through foot vents,,then after a while it changes back to high mid vent.

I ended up trading my 99 Regal in because of multiple AC problems between '04-'06. (Around 80,000 miles on the odometer when it started) The automatic dual zone control box was at fault twice at $800 a pop (out of warrenty after the first replacement..12 mo warrenty, died at 14 mo).

They needed to remove the dash to get at all the stuff.

The complete system was replaced, compressor twice (lifetime warrenty).

You cannot live in Florida without AC.
