Heater problem

[Grizz333]

2008 mega cab with 5.7 motor. I have little to no heat on the driver side no matter which setting. Nice and hot on passenger side. After reading and watching videos i was convinced it was a broken door or actuator problem, but i have taken apart the dash and removed the hvac box and i have no broken doors and the actuators all run when given power. I am now stumped. Any other things i should be looking at?

Are the heater core hoses both hot?

Could there be something wrong with the controls ?

Replaced the heater core at the request of a mechanic friend. Put everything back together and now the truck wont start. b210d code on the reader. The fun continues.

Your battery is real low on power b210d

disconnect your Negative Terminal
Put it on a charger for no less than 2 hours, more is better

If the battery is 4 or more years old, it may be time to replace it

Turns out i had a broken wire right under the steering wheel. But the new heater core did the trick as i have good heat on both sides now. Took the truck for a test drive and now my cruise control doesnt work. Weird thing i will have to check into now.

If you have any trouble light, the Cruise Control will not function

Ended up replacing the brake pedal switch and now we have everything working again. Thanks for the help everyone!
