Getting the HVAC in my truck fixed

I drive a truck for a living. I put an average of 710 miles a day on my vehicle, and some days I don’t feel like driving 7 miles. When my Heating and A/C plan went out, I had to continue my run. I still had 150 miles to go before I reached my next pick-up, where there was also a nearby garage that could repair the Heating and A/C system. By the time I got to the garage, the Heating and A/C expert had already gone home. I knew I couldn’t spend the night in the truck without any heating. Luckily, the truck plaza I was at, had several diners and one well-known hotel. By the time I walked to the hotel and got my room, I was shivering. I had been in the south earlier that morning, where the temperatures were in the eighties. I was now shivering with fast dropping temperatures that were already in the thirties. I got into the room and headed over to the control unit to get some heat in the room. I then turned on the shower and waited until the water was steaming, so I could warm myself from the outside in. I headed to a diner for a fantastic meal and then I went back to the room. The Heating and A/C plan had quit working while I was eating, and the room was almost as freezing as it was outside. I called to the front desk and asked if they had Heating and A/C techs in-house. Five minutes later, there was someone there working on the Heating and A/C system. He said he just had to hit the reset button, and I had excellent Heating and A/C for the next 3 days.
