Toyota Repair: Toyota MR2 -1991, toyota mr2 1991, blown fuse

Question
I'm trying to figure out if I have a blown fuse or bad relay for my heating and air conditioning system ...Both will not run as well as my power windows...I did find a blown fuse for my radio and clock...all inside and exterior lights work...this came about by improperly jumping the battery...

Answer
You will need to replace the 100 amp alternator fuse, it's located in the fuse box under the hood near the engine, it doesn't just pull out because it is bolted in with two small bolts, you can release the plastic holder by prying on the release tabs and pulling up on it then you can remove the bolts.
