Had a scare today... left Dot in the van with the A/C running for a couple hours. When I came back the A/C hose port assembly had melted and fallen away from the window, was just generating heat and dumping it into the van until the A/C unit itself had overheated and tripped the breaker... it was scary hot in there and poor Dot had emptied her water bowl. Thankfully she seems to be doing okay again after cooling back down.
Following this incident I'm putting the other repairs and refit on hold until I finish building the new hose port assembly I started this evening... fabbed a steel bracket I can screw into the door and mount coroplast panels to (cardboard will be used until I obtain the coroplast)
