Removing Fuse Box- 86 560SEL
 

Hello, everyone. The 560 still has no HVAC systems operable, and, although I haven't been driving her lately, since I will start work on her soon, I wondered how hard it would be to remove the Fuse Box, so that I can get to the 30 amp fuse that was placed under it for the blower. I checked with the dealer who originally sold the car, and the service manager said that, according to the records, the car came in for a HVAC- No Blower complaint in '93, and it was due to a blown fuse. He checked with one of the Service Tech's, and he said that on all of those cars, the way that they would rewire the blower, was to insert a fuse block on to the wire under the oe fuse box. So, I need to remove the fuse box to get to see if it is the fuse or not. However, I am fairly sure that it must be the fuse, as I have been under the dash and there is no voltage going to either the blower motor or to the regulator, and all of the wiring appears to be in order.

Thank you for all of you help,
Dave Grady

The fuse box is held together with just a few screws, 2 or 4 can't recall offhand. The fuse panel then lifts off. Most of the 30 amp external fuse update will be mounted to the left inner fenderwell. The wires will pass into the fuse box through one of the rubber grommets on the front end of the box, To install, lift the fuse block off the box, feed the wires in, attach the two wires to the correct fuse position and reassemble. I can't see anyone placing the 30 amp bar fuse under the fuse box.

agreed all those 30 amp rectangular boxes were placed on the false firewall close to the brake booster and the fuse box.it has a cover which pops up.you probably have a hairline crack in the fuse,but if you dont suspect the blower regulator.
