The reason why your coolant temp gauge goes up when at a light is because no air is going through your radiator hence nothing is cooling down your coolant. When you start going air flows through the radiator and cools down your coolant.

First things first check the connectors, wires, and fuses to make sure they’re in good condition

Got a raidator fan thermoswitch on that car? i would check that first. unplug it, bridge the connection, if your fan turns on then, theres your problem.

Usually mounted in the thermostat housing, i've ripped a pic off the net to show you, not sure if it is off a 420a, it will be similar either way.

The 2g 420a doesn't have a thermo switch (only 1g has it). Fans are controlled by the PCM based on the 2 wire ECT sensor (what previous post shows) and AC on/off.
