Question about 1997 Jeep Grand Cherokee
The blower works but when you turn it up on high only cold air comes out. When its on low warm air will come out.
It's possible you are not getting enough coolant flow to your heater core. Try pulling the hoses off the core, blowing it out with air compressor, fill with water and blow out again. Try this about five times and see what happens. Alot of times these cores will plug up or have restricted flow. They will blow warm at low speed but it won't flow enough hot coolant through to stay hot on high blower speed.
