Nissan titan 2010 no heat or cold control,no middle,just very hot or very cold,what can be the problem?thank

Check the compression on each cylinder and the head gaskets as I had a couple of cylinders leaking to each other and worn rings that made it a pest to start first thing in the morning or after a couple of hours
is it using coolant much if so it can indicate the gasket is leaking

probably a good idea to visit a nissan technician as soon as possible

What is VBC? Ah, probably Variable Blower Control? my guess you got wires crossed, or a short around the control or even direct short to hot (12vdc) wire. Double check your work, wire connections. Instructions? with the new? double check.

Take back To Nissan dealer,warranty will cover.

That is natural. It is the clutch engaging on your A/C compressor. You will also notice this sound when you turn on the windshield defrost.

vac or elec door actuator broken i'd say

OK on the truck side, brake controller harness wire colors are:

RED = +12V (Hot at all times, even with truck off)
RED/GREEN = Stop light (Hot when brake pedal is depressed)
BLACK = Ground
BROWN/WHITE = Brake out (variable voltage to trailer brakes, 2v-12v)
RED/BLUE = Dimmer (not used on most controllers)

On the controller side (these are pretty much universal):

BLACK = +12v
RED = Stop light
WHITE = Ground
BLUE = Brake out

I changed the thermostat on mine never helped at all, then I turned my heat button to where the dot on the dial was even with the end of the red mark and I have great heat now
