I searched the threads before posting and couldn't find my same issue. I have a new to me 06 ram 3500 CCLB 6spd 4x4 330k trucks runs very well no smoke or leaks! Typical rear doors issue I'll fix that... However with winter here I have my heat going and when I kick the wipers on the blower shuts off when the wipers complete there cycle and the blower stays off for about 5-15 seconds then blower turns on again by itself. The blower went out couple days ago I would have to bump it for it to blow again here and there and then it finally gave so there's a new one in there. All speeds work on wiper and blower. The engine cranks for about 3-5 seconds cold or hot start LP works no codes either but I'll figure that out any help or advice is appreciated thanks in advance
