I had to open my mouth to my wife about how lucky we have been with no real issues without butler in the last 5 years and sure enough our van stopped working right in the middle of a big job. When you would turn the blower switch on nothing would happen but if you let the van sit for about 5 to 15 min it would turn back on. It ran for about 30 min then it shut off again. Check to make sure filter clean, waste tank not full, everything connected, no bad fuses and so on. We let it sit for about 20 min and it started again. It ran for about 1.5 hrs and then shut off again. We where able to finish job even after van turning on and off 5 times. Does anyone know what it could be and I am also mad because I called butler a hour and half before they closed and the phone was busy but right at 5;01 their phone went to we are now closed for the day. Come on butler what a bunch of bs. Thanks for the help!
