760 T heater fuse gets really hot?

[newsman]

The fuse just gets really hot when the fan is running, if left on high it eventually melts the plastic of the fuse and then starts to melt the fuse box, which is starting to sag. Any suggestions.

Ensure that the connectors are tight and not loose enough to introduce high resistance which will act like a small electric fire.

Cheers, Peter.

You may have to replace the connectors in the fuse box at this point. You should measure the current draw with a multimeter if you have one, but it might be a better idea to just replace the fan motor, they're under 20 bucks here if you ask for one for an '87 Chevy Citation or Celebrity, exact same motor, looks like you're in AU though so I have no idea if these are commonly available there.

The fuse contacts have burned up. Same thing happened to us (same fuse, same model/year). I had to move the fuse, which entailed pulling the fuse / relay assembly out (fairly easy - release the tabs at the side... I think the radio has to come out though). I don't recall the position I moved it to, but there weren't a lot of candidates. I think I cut and spliced the wire, but it has been a while. I recall it wasn't a big job.

If you need to know which position I used, I can look tomorrow.

Aren't his fuses on the end of the dash covered by door when closed and his relays next to his right leg inside console? Or was that only after 1988/9 (Facelift).

Cheers, Peter.

Only know about the US version, but the fuses in the US 85 760 are in the center console, with the relays. There aren't any conflicting pictures in the Haynes, so I suspect it applies to all the '85s.

Only after the facelift. Earlier cars have the fuse/relay box tucked in behind the ashtray in the center console. Looks like a pain to get to until you realize the whole thing slides out fairly easily making everything accessible.
