My heater blew a fuse a few weeks ago for no apparent reason, I went out, got another fuse, and put it in...it came on, and within a minute the fuse box started smoking, I looked down and the contacts of the fuse started actually welding itself to the fuse box contacts...I quickly removed the fuse and inspected it, and the fuse wasnt blown, but both contacts on the fuse had visible damage. It was the right amp fuse I believe(the original glass fuse was still in it, it was a 14 amp), however I cant find a 14 amp glass fuse to save my life, so I went with 15 amps, and even then I had to use a physically smaller fuse since the longer fuses were about 1-2 millimeters too wide. Has anyone experienced this problem before? any suggestions on where to begin? the heater fuse is the only fuse that has this problem...the radio plays off the hot contact of the fuse panel just fine, no melting or blowing up of anything...its just when both of those sides are connected the contacts melt but the actual fuse stays intact. I have a 1985 Prelude junker with a standard fuse box... How complicated would it be to convert? or is it even possible? I hate glass fuses, much easier this way, and it would open up extra spots for fuses for other future things.
You have a short in the blower motor/heater circuit.Or a blower motor on its way out...OR a blower motor resistor shorting out/corroded.As for changing the fuse box to a modern one... Get a painless wireing set up or a Ron Francis set up and re-wire the whole car...You will basically be doing the same thing if you try to put the honda fuse box in it...Good luck!!!
If its arching where the fuse is touching the contacts, Then this is the problem area. I use a small round wire brush, Such as a rifle barrell cleaner. But be sure to take the battery cables off before cleaning.
locating the problem and correcting it will be a whole lot less work... you will have to fix the problem anyway, even if you rewire the complete car... ...Frank...:Handshake
