No - access to all vehicle modules (including the BCM) is through the OBDII ALDL connector.

Any part store can sell you a BCM for your truck. It has to be programmed for your truck though. You'll have a 1 in a 1000 chance of getting one from a junk yard the will run your truck. Because of the security issues. It also has to be the same engine and transmission to work properly.

I would look at the air blend doors first, it sound like they are not working or your control in the dash is not working send a signal to them. they work by changing the air from hot to cold or in between.

Probably a heater core starting to leak(better take care of it now before it blows wide open!).You might be lucky enough to find a loose heater hose clamp/defective hose is allowing coolant to seep onto the core,so check that first.

i would guess that there is a leak in heater core is the smell just in car or outside too

its in the engine compartment in the fuse box on the drivers side next to battery

One possible cause for this would be is the mass air flow sensor which is located on the air filter box. I recently paid around $90 dollars for one. I don't know if this part can be checked or not. Another likely cause is the fuel pump. I had this problem recently and this was the cause. The pump is mounted in the top of the fuel tank. You can have someone check the fuel pressure coming to the fuel rails on top of the engine to verify that this is the problem. The easiest way to change the pump is to remove the bed, giving easy access to the pump. These pumps are still rather expensive, in the range of $200 dollars new.

contaminated fuel, fuel filter clogged, injector ports caked.

Did you replace the line al so.If not line may have cal.

follow top hose to engine. and you will find it. the hose goes directly on thermostat housing, do not forget to replace with new gasket. on housing, remove the left bolt then the right bolt then pull off housing, then you will see thermostat. drain radiator some to keep from losing to much anti-freeze. Good-day!
