A friend of mine has a 2004 Dodge Ram. She recently ran into a problem where her AC was working as long as she was not idle. Becoming idle, the AC would stop. Someone checked it out for her and told her that the raeson was that a fuse had blown and with that that the fan was not working. Can someone tell me how to go about fixing this and it is hard to fix?

Replacing a blown fuse is as simple as locating where the fuses are (from the owner manual) - pulling it out and sticking in a new one.

Easy shmeezy - and the fuses run a few bucks for a dozen.

Also, many autos do not engage the air conditioner compressor at idle, ( to prevent engine overheating) so at a light or stopped in traffic, it could get sticky.
