Passenger side Defrost

Cannot feel blower/flow from passenger side defrost vent. All other vents and settings appear to work. For example...I can switch from hot to cold....from feet to vent to defrost....blower motor is fine. Just not getting anything out of passenger side dashboard.:tear: Any suggestions appreciated.

I have a 1989 RENIX, and all I might suggest for your newer generation XJ model is to look to see if the hose connection has parted. Flash light might help greatly, i.e., look directly into the vent to see if it continues on, and on, or look up from underneath dash to that area. Take care of your spine positions while you check the latter view.., just say'in.
