Chrissy, how long / far are you running the car before the temp gauge hits the half way point?

Mine is a new original fit thermostat, and I have my radiator 70% screened off and mine (2007 CRD) still takes a good 10 miles plus to get fully warmed up - and even then the heater isn't exactly brilliant.

(Note: The same engine (Mercedes 646) when fitted to Mercedes saloons had a special cabin heater fitted thats missing in the PT installation - probably it was there for a reason?)

New and never before seen. Here's how to check the temp mix control in a 1st Gen PT Cruiser.

What we want to do is get our hand on the mix door lever while turning the temp control knob. Here is where that lever is located if the vent system was out of the car.

First, remove the center bezel. Pop out the power window switch with a plastic trim tool to prevent scratches.

Next, remove the one Philips head screw behind the window switch.

Pull off all four HVAC control knobs.

Reach into the hole where the window switch was and hook three fingers behind the bezel. You may want to use both hands and hook fingers behind the bezel on both sides.

Now pull and pop off the bezel.

Next, put the temp control knob back on. In the top open space, you will now see the ducts for the vents in the center bezel. These are made of thin flexible plastic.

Take your left hand and gently pull the right outer side of the right duct to the left. It's flexible and should not break. And it will easily pop back into shape later on. Notice the two white cables that are now visible.

Take you right hand and touch the white horizontal cables, then move your fingers to the left. You will feel two levers. The mix door lever is the lower one. Let go of the plastic duct with your left hand and use it to turn the temp control knob back and forth. If functioning correctly, you will feel the mix door lever moving back and forth with the control knob.

If the lever does not move, this will be the likely reason you have no heat since the air will not be passing over the heater coil before being vented into the car.

PS: It appears Chrysler has changed the HVAC vent system considerably between the 1st and 2nd Gen PT's. This task is slightly easier on the 2nd Gen Models and the mix door lever is in a much more accessible location.
