A/C blower motor problem.

I have a trans XE 80 unit. It has a CNT2182 control module. My problem is this. When in A/C mode the fan/blower motor in auto clicks and goes off, then randomly comes back on. It does this over and over. Everything else works fine. Would this be a bad control module or perhaps the start/run capacitor going bad. If the fan motir is in manual in A/C mode the fan motor works fine. /Please

Welcome to the forums.

Do you actually hear a click when the blower goes on and off in A/C mode ?
If you actually hear a click ....... try connecting a jumper from the G terminal to the R terminal of the control board. See if the blower runs normally then. If it does..... there's a problem with the thermostat.

You can use a short piece of wire to temporarily hold on the R and G screw terminals. I use a wire with alligator clips. Make sure you only short the R and G. It can be done with the wires left on the terminals.
