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 !
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?
@@bigrigfix what if I’m driving and it’s blowing pretty cold and when I get to a stop light. It starts to blow cool almost warm. Does that mean I’m just low on freon.
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 ?

hi.....what if the fan is not working from the cabin
@@TaiwoIdowuPeter Check the fuse , relay , and resistor for current . The blower motor may be shorted .
I have a green liquid leak on the low side line ..do I have to change the line

Same here with mine.

good video just curious do you always use wheel chalks to start your truck or did you do that for your youtube channel
Just when I work on the truck.

Sometimes the blower motor plug connection get so hot it get a bad connection. Also the blower maybe bad.
On that truck were would the fuse box be located for the double cigarette plug ins..????
The fuse is located under hood drive side on top of fender.
Do u add Freon on high side or low side
Low side big line.
Low side
