2000 xj. Threw in my 98 long block (cause blown 0331 head).
All fan settings work correctly, but not getting much in the way of heat.
When set to cold, the vents blow MUCH harder than when set to heat. On max heat setting, on defrost, you can barely feel any air coming out the side window vents, and the defrost vents are definitely restricted. Restriction ONLY occurs when set to heat. Cold it blows normally.
Checked the heater hoses. Input is hot, output is cold, as it should be.
All I can think is that there must be something caked on the outside of the heater core, blocking air flow, but I've no idea what the inside of the 2000 HVAC looks like.
Ideas?
