Basic Cars and Trucks A/C Troubleshooting 

Thank for you the video help a lot today I got the same truck. God bless you

On older trucks check your heater coolant lines , if both are hot the shut off valve is defective . The A/C system will not override the heating system . Install manual ball valves on the engine block . Good Video !

good video just curious do you always use wheel chalks to start your truck or did you do that for your youtube channel

I have a 2018 freightliner s2rv. temp coming out of the vent is only 62f.. my pressure on high side are 265 but low side is only 26psi.. do I need a new expasion valve?

I have a green liquid leak on the low side line ..do I have to change the line

Do u add Freon on high side or low side

I got Columbia 2005 heat control switch not blowing and return light flashing...

So my truck ac unit works whenever it wants too , like it’s on setting 4 right now on the heater and it’s not blowing at all .. only randomly it will start working and stop again what could it be ? The blower motor ?

Mine blows cold air only when driving,, but as soon as i get to a stoplight it blows warm air

On that truck were would the fuse box be located for the double cigarette plug ins..????

Can i bring my truck to you i have problem with blowing air when truck is parked?

Can be reset?

How do you reset the AC

My Ac is blown Hot air it just started

How do I recharge it

bad camera very repetative. sounds like your blowfishing .read a book forst.

Very repetitive. How many times do we need to see where the line goes? Move on already
