The radiator may be plugged or the head gasket can let compression gasses into the radiator . To check, run the engine without the radiator cap and look in to see if there any bubbles in the coolant. If there is a lot of coolant moving in the radiator after the T/stat has opened, the water pump is ok. If not then suspect the water pump is not circulating enough water.

Park lamp fuse 20amp located in the under hood fuse box .DRL control module
Daytime Running Lamps (DRL) Control Module
Right of the steering column, behind the IP
Park, Sidemarker, Tail and License Lamps
Voltage is applied continuously to the PARK fuse to the headlamp and the instrument panel (IP) lamp dimmer switch through CKT 1340.
When the headlamp and the (IP) lamp dimmer switch is in the PARK or HEAD position, voltage is applied to CKT 9 thus activating the following lamps:
• The park lamps
• The side marker lamps
• The tail lamps
• The license lamps
The park/turn lamps are the only lamps that do not activate yet receive a current from CKT 9. The park/turn lamps do not activate because the voltage drop across the front side marker lamps is much higher than that across the turn lamp filaments Step

You probably have a short or a loose wire. This is likely what caused the fuse to blow in the first place.

Recommended GM DEXRON® VI, Low viscosity transmission fluid.
Note: make sure you don't over fill transmission and the Montana's transmission are know for failures due to high fluid retention caused by high viscosity transmission fluid from additives or dirty transmission oil and filter.
Thank you for using Fixya and good luck.

I would recommend you check the fuel for contaminates.
Change fuel filter and flush carb.

You can try performing a diagnostic self-test of the DIC.

In order to perform the diagnostic self-test and reset the driver information display, simultaneously press the following buttons for at least 2 seconds :

MODE
ENGLISH/METRIC
The reset is acknowledged with the display showing all segments ON for 1 second . You may only reset the following modes. The reset affects all 3 of these modes simultaneously:

AVG ECON
FUEL USED
AVG SPEED

If all of the segments light as described above, but the same symptoms are still present follow these instructions:

Symptom: Driver Information Center (DIC) Always Displays Dashes

1. Check for a poor connection or an open in circuit 800 (Tan wire) between the DIC connector terminal 15 and the Powertrain Control Module (PCM) connector C1 terminal 15.
2. If a problem is found with the circuit in step 1, repair the circuit and retest. Otherwise continue to step 3.
3. Replace the DIC and retest

key FOB has a bad switch so you have to find a new one. New one will need the micro switches matched to the old one.

Have you checked under the dashboard yet? Today's cars and trucks have two fuse boxes. The first is on the driver's side of the vehicle, usually under the kick flap to the left of the brake pedal. There should be a pop-off cover or box located on the firewall that contains a number of fuses. It isn't likely to be a fuse fault, though.

It sounds like you are experiencing problems with a thermocouple style switch. In other words, when the the switch or device reaches a certain temperature, it switches off.

To find this particular device, you will have to obtain a service manual for the electrical and fan systems and then you will have to find the diagrams that cover the fan. Study them and you will likely find that there is a special symbol there that shows there is a heat-activated or thermocouple switch. If you identify it and feel comfortable handling the job, remove the old switch and swap in a new one. The chances are good that this is the whole problem. I honestly doubt it was a fuse in the first place.

One other suggestion is this, look to see if there might not be a cooling system switch that handles this function. You'll need the service manual for that, too.
