| there is no law prohibiting the company from disabling the a/c, or refusing to maintain it. I went through this with an LTL carrier where I worked for 15 years... Some nights you lucked out, some nights you had to suffer..( I didn't mind unassigned equipment, when you're making 70K) I think the only area this wasn't the case was in the southern supplements, where it was in the contract, they had to fix it, or send the tractor to a facility that could fix it.. |

the fmcsa website says nothing about a/c. as you can see, the defroster does not have to be part of an a/c system, it just has to work. do the idiots you work for know that the truck was designed for naximum mileage taking the a/c into account? I bet they dont get a 1/4 mile to a gallon more. even if they did, they surely spend more than they save because they constantly have to train new drivers, I cant imagine anyone staying long, sounds like your company is run by the new breed of managers. all education and no common sense whatsoever. I would get out fast. they have already proven that they care nothing about you.

S1. Scope. This standard specifies requirements for windshield defrosting and defogging systems.
S2. Application. This standard applies to passenger cars, multipurpose passenger vehicles, trucks, and buses.
S3. Definitions. Road load means the power output required to move a given motor vehicle at curb weight plus 180 kilograms on level, clean, dry, smooth portland cement concrete pavement (or other surface with equivalent coefficient of surface friction) at a specified speed through still air at 20 degrees Celsius, and standard barometric pressure (101.3 kilopascals) and includes driveline friction, rolling friction, and air resistance.
S4. Requirements. (a) Except as provided in paragraph (b) of this section, each passenger car shall meet the requirements specified in S4.1, S4.2, and S4.3, and each multipurpose passenger vehicle, truck, and bus shall meet the requirements specified in S4.1.
(b) Each passenger car, multipurpose passenger vehicle, truck, and bus manufactured for sale in the noncontinental United States may, at the option of the manufacturer, have a windshield defogging system which operates either by applying heat to the windshield or by dehumidifying the air inside the passenger compartment of the vehicle, in lieu of meeting the requirements specified by paragraph (a) of this section.
S4.1 Each vehicle shall have a windshield defrosting and defogging system.
S4.2 Each passenger car windshield defrosting and defogging system shall meet the requirements of section 3 of SAE Recommended Practice J902, "Passenger Car Windshield Defrosting Systems," August 1964, when tested in accordance with S4.3, except that "the critical area" specified in paragraph 3.1 of SAE Recommended Practice J902 shall be that established as Area C in accordance with Motor Vehicle Safety Standard No. 104, "Windshield Wiping and Washing Systems," and "the entire windshield" specified in paragraph 3.3 of SAE Recommended Practice J902 shall be that established as Area A in accordance with ?571.104.
S4.3 Demonstration procedure. The passenger car windshield defrosting and defogging system shall be tested in accordance with the portions of paragraphs 4.1 through 4.4.7 of SAE Recommended Practice J902, August 1964, or SAE Recommended Practice J902a, March 1967, applicable to that system, except that?
(a) During the first 5 minutes of the test:
(a)(1) For a passenger car equipped with a heating system other than a heat exchanger type that uses the engine's coolant as a means to supply the heat to the heat exchanger, the warm-up procedure is that specified by the vehicle's manufacturer for cold weather starting, except that connection to a power or heat source external to the vehicle is not permitted.
(a)(2) For all other passenger cars, the warm?up procedure may be that recommended by the vehicle's manufacturer for cold weather starting.
(b) During the last 35 minutes of the test period (or the entire test period if the 5-minute warm-up procedure specified in paragraph (a) of this section is not used),
(b)(1) For a passenger car equipped with a heating system other than a heat exchanger type that uses the engine's coolant as a means to supply the heat to the heat exchanger, the procedure shall be that specified by the vehicle's manufacturer for cold weather starting, except that connection to a power or heat source external to the vehicle is not permitted.
(b)(2) For all other passenger cars, either?
(b)(2)(i) The engines speed shall not exceed 1,500 r.p.m. in neutral gear; or
(b)(2)(ii) The engine speed and load shall not exceed the speed and load at 40 kilometers per hour in the manufacturer's recommended gear with road load.
(c) A room air change of 90 times per hour is not required;
(d) The windshield wipers may be used during the test if they are operated without manual assist;
(e) One or two windows may be open a total of 25 millimeters;
(f) The defroster blower may be turned on at any time; and
(g) The wind velocity is at any level from 0 to 3 kilometers per hour.
(h) The test chamber temperature and the wind velocity shall be measured, after the engine has been started, at the forward most point of the vehicle or a point 914 millimters from the base of the windshield, whichever is farther forward, at a level halfway between the top and bottom of the windshield on the vehicle centerline.

From what I could tell, trucks use an automotive type AC compressor. It won't suffer nearly the same parasitic losses that a car or pickup might suffer from the compressor engaging. Hell, in my KW T2000 I couldn't tell the AC compressor was even on, except for the occasional engaging of the cooling fan, which probably robs more power than the AC compressor.
It's not like a motorcoach, which has a huge multi-cylinder ac compressor that has the displacement of a small car engine.
FWIW, when I drove for Pepsi locally, I drove a POS GMC TopKick with no AC on a 100+ mile drive one way across the desert. OK in the mornings but on the way home in the summer afternoons with 100+ temps. F--- that! I quit after being promised time after time that I'd get a more highway friendly truck with AC. |

For many route vendors, the distance from one stop to another is so short that you would not be running long enough to cool the truck down, and I can see where a route company such as a beer or a soft drink distributor would not want trucks left to idle while accounts are being serviced. |

| The company is called Chesbay Distributing Company. The funny thing about this whole situation is that we have one truck that has working a/c and it was given to the senior driver. Guess what he quit a month ago. But believe it or not there is plenty of time in between stops to cool down the truck. i am talking about a tandemn axle 18 wheeler tractot trailer not a single axel bay tailer with rolling doors. |

| The other factor that many of the bean counters overlook is that if you don't have AC the truck will incur additional drag from having the window rolled down. Although most of the old vocational trucks were talking about here are aerodynamic bricks anyway. |

Living in Arizona and driving locally, I would not drive a truck that did not have AC. I would find a new company
VaBulldogs13U wrote: Hey guys a quick question is there a reg about having a/c in your truck...at work we were talking about it someone said if it was installed at the factory then it must work according to a reg.. I havent heard of that one. Before you guys ask the company I work for removed and disconected the a/c in all the trucks to "save on gas". That why I want to become an O/O to get away from these guys. It gets real humid in this part of Va |
