l have a 1995 subaru impreza L AWD. when l pop the hood there is a small box in the upper left hand corner, it is a small fuse box, good for one fuse, and is labeled FWD, l would like to know if there should be a fuse there as there isnt right now, and what does this do, and if there is a fuse how do l operate the function it provides?

Unless you are noticing something in the vehicle that is not functional, l would not worry about it. It is typical for autos to have unused slots on fuse blocks and relay ports etc. Either your vehicle was not equipped with whatever option it was for, or it is a fuse block used on multiple vehicles made by subaru and your impreza did not even have an option for whatever it did.

That fuse box is there to put the vehicle in to Front Wheel Drive. Since your car is AWD the fuse box is meant to be used when the spare tire is put on. Check your owners manual to find out how to properly operate it. l am not sure if the fuse needs to be installed for it to go into FWD or if it needs to be removed. l do know that if you are operating in FWD a light would indicate that on your dash.

Its an emergency fuse box l think since all subarus come in natural awd nowadays, it is a backup in case of any axel problems so if ur awd is not working a fuse couuld be used to initiate the front wheel drive system so that it will carry on smoothly for a while.

its for the FWD on the older automatics. if your manual you need not worry about it

Very simple.

Only Automatic Subaru is have this.

The reason it is there is if ur car were to break down & a tow truck had to tow u to the garage, u have to put a fuse in there to disengage the AWD (making the rear wheels spin freely).

Or else if he is towing u car down the road with the fronts in the air & the backs on the road & ur AWD is still engaged, then it can do serious damage to the transmission.

Most tow companies have flatbed trucks now, but there is still a chance.
