Sorry to hear about for Father. I was in a truck 3 weeks ago with no ac and the temp was 104 with a heat index of 110. Add the heat from the asphalt in the bed and it was 120 at head level in the cab. I have been doing night work on I-95 near Kings Domion, hauling millings. It seems that 4 wheelers are even more crazy at night then during the day. Between backing with bright lights in your mirror to trying to get up to speed and merging onto the highway, some nights it's a e-ticket ride. :-). This should look familarure to ya. http://youtu.be/DFR4MW9YuK8

I just shot an e-mail out to MACK today, concerning this very issue. The only differiance is that I am driving an 2004 Granit Series, Model # CV713. 5 of our trucks have this same issue only every time this happens, the low air buzzer comes on and it is driving me crazy!!!! I pulled the dash and went stright to the wire harness that plugs into the dash gauges. All of the "Locking" grips are in good shape where the male plugs into the female, yet when I move it just a hair, all the gauges go dead and on comes that stinkin buzzer. I will edit this post when I get a reply back from Mack. This is a copy of the e-mail I sent them today. "I am requesting that you forward this e-mail to the proper department. We have 20 Mack Trucks in our fleet. There are two issues that several of our trucks are having. I have attached a picture of the data plates for these trucks. Problem # 1. The low air buzzer is going off on a constant basis. If the truck is run for 8 hours, the Driver will listen to this for 7 to 7.5 hours. I have pulled the instrument panel off the trucks and this is what I found. The connection from the wiring harness that plugs into the dash pannel is in tact. All of the "Locking Tabs" are in place between the two connections, yet when you move the connection just a hair, all the gauges go dead and the low air buzzer comes on. It is my opinion that when this happens, the truck thinks it is being started each time and that is why the buzzer is coming on. This problem is in direct violation of FMCSA's requirements not to mention a distraction to the Driver. Is Mack aware of this issue and if so, how do we fix it? Problem # 2. You can open either the Drivers door or Passengers door and lock the door with the key or the lock slider switch. Yet when you close the doors and lock them with the key, YOU CAN NOT UNLOCK THE DOORS! I have attached two pictures of the door lock mechanisms. There is no slop or binding points. I have removed the interior door panels and inspected all the mechanical linkage and everything seems to be in tact. Last Friday evening, I sat in a parking lot for two hours removing the rear glass so I could get back into my truck. Please keep in mind that I live in Northern Virginia and I have been in my truck, driving into DC and had people jump on my truck as I am going 1/2 mph due to traffic, just to steal a pack of cigs off my dash. I use a Rand McNally 720 GPS valued at $450.00 along with $800.00's worth of tools that I carry. When I go into a 7-11 to get a cup of coffee, I need to be able to lock my truck. 5 of our trucks with the same model # of the picture I sent you, have the exact same problem. Is Mack aware of this issue and if so, how do we fix it? My credentials are as follows: 34 years as a Class A CDL Driver. Hazmatt, Tanker, Doubles & Triple Endorsement.

Thank you in advance, from your #1 Bull Dog Lover. (Gggrrrrraaaaaaawwwwwwwwwwlllllllllllll). ;-) Dana Tucker

Hello and God Bless. I have been grinding gears going on 35 years now and still learning every single day! I recently came in from OTR and am running a Mack Quad Axle Mud Bucket that is permitted up to 96,719 #'s. I do this in and out of one of the most congested areas in the USA, and lovin every second of it. I run a "Big Dawg" dash cam and every once in a while, get a good video concerning what happens over the road. I look forward to learning from this forum as well as particapating on it as well.
