Thank you all for good answers. I`ve changed the resistor pack next to the fan, the connections seemed okay, but a little bit dirty/rusty. How can i change this connection if this is the problem? Where do i find the fan connector? Is it the two wires coming out from the blower motor? If so, it might be what`s causing the problem, because the connection seems to be pretty bad.

Hello. I got a strange problem with my blower motor. Sometimes it works and sometimes it doesn`t. I`ve changed the controller for the speeds. Which helped because before, it only worked on full speed, sometimes. (Now it works on all speeds when it works.) Then after changing the controller that sits with the fan I`ve still got the same problem with the fan completely shutting off and other times working perfectly fine. It seems like there might be a weak connection in some wiring connections? Has anyone else had the same problem or know what could be causing this strange problem?
