2005 GC Overheating at Idle - Just replaced blower motor resistor

My Jeep is overheating at idle, but cooling down while moving. I am also able to bring the gauge down by turning the heat on and turning off recirculation.

I just had to replace the blower motor resistor as it stopped functioning. I am starting to wonder if somehow this is a related problem.

I just checked the reservoir and it's bone dry. I'm going to add some fluid today, but just wondering if this a head gasket or another issue.

I would start with the thermostat and radiator cap (cheap).

Possibly blowing by a weak cap. Easy to get to, start there.

Almost definitely a bad radiator cap, super common issue.
