Has anyone had any issues with your front A/C not blowing hard in your suburban? The fan is running properly on all speeds. The fans is actually spinning (not slipping on the shaft) The dampers are actuating to the proper settings (floor, vents, defrost, etc.) but it just does not blow very hard. The mechanic that I use said the evaporator is not clogged up and these vehicles are just that way. The rear air blows wonderfully so does anyone have any experience with this problem or a possible solution? I have owned the suburban for a year now and it has always had this poor performance. Thanks for the help.

I took the fan motor out of my 98 and blew compressed air thru all the ducts/heater core etc, the stuff that came out of the ducts is amasing. Mine was an ex farm truck and had seen lots of dusty roads
Also my RPO listed it as having a cabin filter but I never did find it before I sold the truck
