The dimmer switch is bad .

check the harness at the door hinge

Very common problem on these cars. REplace the hazard switch

Believe it or not, new thermostats can be bad. Did you maybe get some adhesive on the thermostat preventing it to open fully? Is the thermostat installed with the crown up? The only other thing that I can think of, if it's a closed cooling system and the wrong radiator cap is installed, it won't hold the pressure, therefor overheating. The other thing may be the water pump. Many times the impellers will wear down internally causing to low of water flow.

I swear this used to happen to me. I'd hit the top of the dash and it would stop. No lie

were the motor & trans mounts checked?

first off have a look in the radiator see it there is a lot of bugs and debris stuck in it, if so clear it out with a hose being careful not to damage the cooling fins. then let it run until the fan cycles on and off a couple of times and make sure it is working properly if so you may have a bad temperature sensor. Was it doing this before the radiator was replaced? If not you may have air in the system start the car run it upon a set of ramps remove the radiator cap and let it idle until it burps, you will know when it does because the coolant level will drop in the radiator. while it is on the ramps get a flashlight and shine it up to the head of the vehicle and look for traces of coolant, if you see a stain the lower intake gasket could be leaking they are known for that as well. the turn signal thing could be a brake light switch that is dirtya bad socket,a burnt bulb.

See the park lamp relay, I'm not saying the relay is faulty, but, you might be able to use jumper wire on load side of relay, if lamps work, the problem is on control side of relay, for some reason. The load side of relay is that line with arrowhead. There could be other issues.

The linkage to the trans may be bent
