1999 Jeep Cherokee

Heater problem
1999 Jeep Cherokee 6 cyl Four Wheel Drive Automatic 160, 00 miles

my 99 jeep grand cherokee has no heat, the air blows out but blows out cold air. It actually blows out whatever the temperature outside is. If it is hot outside I get hot air if it is cold I get cold air. Please help, no one can tell me what is wrong with it

First feel the heater core hoses with the vehicle hot. They should be hot. Tell me what you find.

Really sounds to me like your blend door is not working in your car and is stuck in the middle of the temp range.
