My 98 Jeep Cherokee is only blowing cold air. The A/C compressor was replaced in the summer. I replaced the thermostat. When I switch the control from hot to cold, it certainly gets cold. When I turn it to hot, it doesn't get much warmer. What are the likely steps to find the fix? Is the heater core next? Relays?

The thermostat been replaced-could be the air mix/blend/ mode doors problem -vacuum and actuators.

How's you antifreeze level? If your low on coolant then the heat will become affected.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
