   Failure of a $70 thermocouple sensor in the air conditioning unit requires replacement of the entire evaporative cooler, which requires removal and reinstallation of the entire dash from the vehicle. This should be a part serviceable without such extensive work.

   My 2021 Ford F 450 will not actuate the electric over hydraulic brakes on my gooseneck trailer. I was hauling my tractor to one of my hay fields when a car pulled out in front me. I apply my foot to the brake pedal and the truck and trailer did not slow down liked it use to and I almost rear ended the vehicle that pulled out in front of me. After this I try to apply just the trailer brakes using the brake actuator on the dash and the trailer brakes never operated. I check my fuses and they were good and I checked the trailer using another truck and they worked. I then checked the trailer wiring connections on my truck and they were good. I have done a manual reset on my trucks programming and the truck still will not activate the trailer brakes. Please help.

    While towing my gooseneck horse trailer the tailgate opened randomly. I had towed for about 20 miles and got off the freeway and was driving through a parking lot when it happened. When I turned the tailgate struck the horse trailer causing body parts to fall in the roadway which could be dangerous to other motorist. Normally when the tailgate is open a message appears on the dash. No message was received, no buttons on keys or dash were depressed to cause this to occur.
