Jake - 2008 Frieghtliner 3500 170ext Mega Roof
I recently purchased a 2008 170 mega roof Freightliner sprinter. During initial test drive, I noticed the AC was not blowing cold. I discussed with the owner and he had said it was working just a month ago, but hasn’t used it since. Well I needed to drive it to Florida so I needed AC working before making the drive. He offered to take it to his mechanic to check it out. Since it was the exact model I was looking for with the extra high roof, I was willing to work with him
Long story short, the mechanic drained the system and refilled it. AC WORKING blowing ice cold
Drove that evening for 6 hours until I made it to Virginia. Ac working beautifully. Spent the night in a hotel, got up the next morning, drove for another 3-4 hours while the ac worked great (it was in upper 80’s going through the Carolinas). Stopped for 10 minutes to grab lunch, came back out to the van with NO COLD AIR COMING FROM AC. Noticeably not cool air coming from vents. Well it was a long and not 8-9hrs to south Florida, frustrated, but happy to have secured the van for our build.
Confused at how it could go from working to not working so quickly. A friend and I have checked the fuses, none of which are blown. We connected the compressor/clutch to a 12v battery and it gives us a click sound. Could the Freon in the system be low, causing the pressure switch to stop the ac system from engaging?
We tested the wire going to the compressor with the van running, and ac turned on, and got a 0volts reading, when I’m assuming it should be 12v going to the compressor.
Thinking of having the pressure tested. I guess my question is, will low pressure set off the ac pressure switch, causing the system to NOT cool
Thanks so much in advance, been combing through these forums, so much information and different scenarios. Figured with all the knowledgeable members I might be able to get to a solution quicker by (and this is VERY hard for me) asking for help..
Cheers!
