Help with Volvo VNL780 A/C

Hey fellas, on my volvo the AC wont work. It happend yesterday while i was idling and it was hot so i turn on the ac and i noticed its blowing warm air. I dont see any water leak on the passenger side under the truck usually when ac work properly there is water down there from condensation i think. I went and check the ac compressor first thing and i found this. If someone can help please share. Thanks!

 

I have Volvo 2015,

Just spend $400 for nothing, frion is good, they replace pressure sensor but still there is no power to AC compressor. Any toughs ?

 

Maybe some fuse ?

 

They check all fuses they are good unless is there something that we don't know

 

How about the compressor ? Have you replaced it ? Sorry maybe u post earlier but i had no chance to read the previous messages .

 

No we did not, we had truck on road this morning and they ware trying to fix it but nothing. They check charge is good, they check fuses no issues so they replace pressure sensor and still no power to compressor so they give up charge as 400 and said take to dealer. So it cold be compressor? Even if we don't getting power ?

 

I’m not that sure it could be the compressor i’m just guessing i’m not mechanic and don’t want u to spend the money replacing good parts.

 

Dash control

 

Thank you for reply, we will check today. Let you know

 

When you change to on and off control is working
