2010 387 AC not blowing cool at all.

Is the compressor moving,did you look to see? OMG I know what u r going thru...uugh
That'd b the 1st thing I'd check..I guess the silver lining is sounds like u don't have to pay for it,as it sounds like u r a comp driver... I've never gotten that lucky for it to b just a fuse.

 

First, the fan has to be on for the AC to work. Second, flick the switch to recirulate cab air or MAX and that will shut off the hot outside air except for what comes in the windows. Third, make sure the temp. control is on cold. Fourth, stop somewhere and have your codriver turn the AC on and off a few times and see if the compressor is turning. Make sure the selectors are in one of the AC posistions and the fan is turned on. If the drive belt is turning the clutch but the compressor is not turning it could be a fuse, a broken or shorted wire, a loose connection at the compressor plug, or on the hi-lo pressure switch or in the dash controls or cold control or the clutch is bad, a bad hi-lo pressure switch and probably a dozen more things. Something is not giving power to engage the compressor or the system is way way low on gas which also shuts down the compressor to protect it. In this case it would be best to let a shop take care of it. If the compressor is turning and it doesn't get cold then most likely there is a leak in the system. You could buy some cans of gas and a fill tube at Wal Mart and recharge it to get you by until it can be fixed. There will be a label somewhere on the firewall or around the lines that tell you how much it holds or fill it until the engine fan comes on and then put maybe another 1/2 can. (small cans) The clutch is an electric clutch and the drive pulley is the center section of what you can see on the front of the compressor. The belt drives the clutch, then when powered on the clutch grabs the drive pulley that turns the compressor. No company I ever worked for held AC work as much of a priority but I #### sure do.

 

If it doesn't blow cold stop at ta sapp Bros ect. Ask them to charge it up. I'm thinking the condenser could have a leak

 

Probably needs to be drained and charged up. If not then its most likely the compressor.

 

I believe A/C is a really big money maker for truck garages.Ive never had anything as easy as putting in freon.always the works cha chang!

 

All AC systems leak. I keep mine topped off with gas as I feel it going away a little bit. Very easy to do yourself with a fill kit and a can of freon. Believe it or not my system hasn't been touched in 5 years now except for cleaning the filters and keeping it topped off. PS: You should run your AC every month for 10 minutes or so even in the winter to keep seals, etc. lubed.

 

Well I sure would, if they say NO then I WOULD GO DIRECTLY TO THE SAFETY DEPT OR THE OWNER OR THE HEAD DUDE IN CHARGE and ask them if they would prefer a multi-million dollar lawsuit when you rear end something or somebody because the windows are fogged up and won't clear BECAUSE YOU GUYS ARE TOO DAMMMM CHEAP TO FIX THE AC........if they still don't get it then I would take that bus and look to work elsewhere.

 

There are no rules that require the A/C to work. Your options are to make a case to convince them to fix it, or find a job with a company that cares about their employees. I'd start with the guy that wont fix it for you, give him another chance and explain why working A/C will help you and the company. You'd be best not bringing up the fogging issue unless it really is an issue. Focus on the real issue, you're hot and uncomfortable. This makes for a poor attitude, more aggressive driving, it makes you tired even if you sleep well (which you can't due to the heat). An uncomfortable driver is a less productive driver. If he refuses, go above his head. Just keep in mind that they do not have to fix it, so threats wont help you case.

Their should be some rules for A/C, at the very least a requirement for team drivers, unfortunately there isn't and some companies would rather find a driver willing to deal with it than spend money fixing it. The downfall of A/C is the lack of understanding how they work and how to maintain them. The initial cost of the equipment needed is also high. A company fails to train mechanics to properly fix them, so maintenance costs of A/C are much higher than they need to be. We really don't have many A/C issues because when we do, we fully diagnose and repair them. We don't just shoot refrigerant in a low system, it's low for a reason and I want to know why. We have an A/C charge/recovery machine, a sniffer and a dye kit. There's no reason to keep adding refrigerant
