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 !
@@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.
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?
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 ?
@@fastrunlogistics3560 el gas refrigerante se revisa con los manómetros, la presión baja debe andar entre 20 y 40, 50 como máximo, y la presión alta debe andar entre 250 y 300, si la presión alta anda en menos de 250 sentirá que enfría poco al estar estacionado y que en marcha enfría más, lo otro que puede estar pasando es que el compresor no esté trabajando al cien por desgaste de uso, así que con los manómetros puestos y el vehículo estacionado acelerelo y vea como se comportan las agujas de los manómetros.

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.
I have a green liquid leak on the low side line ..do I have to change the line
Can i bring my truck to you i have problem with blowing air when truck is parked?
The fan Stays on When it parked.

Sometimes the blower motor plug connection get so hot it get a bad connection. Also the blower maybe bad.
I got Columbia 2005 heat control switch not blowing and return light flashing...
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.
Mine blows cold air only when driving,, but as soon as i get to a stoplight it blows warm air
Same here with mine.
Eso es porque le falta gas refrigerante...
