2001 jeep cherokee limited both heated seats stopped working and passenger side blows cold air only. what do I do?
These 2 problems are not related. The heated seat system and the heater/ac are separate systems. If you have the dual zone heat/ac system (passenger/driver) then the temperature blend door pivot has broken. I see this a lot in these vehicles. It will involve removing the dash and hvac unit to be able to replace the blend door. This is something you should have your dealer do, or an independent technician who is familiar with this type of work. The part itself is not expensive but the labor will be (about an 8 hour job). As far as the heated seats, what I see is the actual heating elements burn out. There is an updated repair kit to fix this that you can purchase from the dealer.
