canineseven Posted August 23, 2022 Share Posted August 23, 2022 Stumped on an issue our CXU has been having. A/C is working well, but after a bit the airflow reduces. Can hear the fan running, and changing speeds when turning it up, but air is restricted from the vents. Push A/C button off, and air returns in about 30 seconds or so...push A/C and works fine again for a bit. Evaporator isn't freezing up, seems to be maybe a blend door issue? Any help? Thanks!
