My blower recently went on the blink. Sometimes it blows, sometimes it doesn't. Often, when I accellerate, it kicks on. Now that doesn't even seem to be the case. This leads me to think that there may be a loose connection. I check the 20 HVAC fuse and it was fine. There is a fuse block, but I wasn't sure if this is something I should be messing with. Can anyone help me solve this puzzle? It's been kind of cold here.
