Wire on C200 conector going SUPERHOT

[mgromero]

Hi guys,

the VIOLET wire in the conector C200 is getting super hot to touch whenever I turn on any of the 4 positions of the blower fan.

If the blower fan is turned on in pos. 1 = wire getting hot at a slower pace
if the blower fan is turned on in pos. 4= wire going thermonuclear quick.

The strange part is that the wire is getting hot only in the ignition switch side of the connector. See picture for details. I can assume that the wire was changed or reparied in some point, because it have some tape.

Any clue? this is driving me nuts and I dont want to go up in flames.

Pull fuses 4, 5, 6, and 12. Does the blower motor still work?

have you taken a look at whats under the tape? Poor connection would produce heat

Yes, also be sure the wire gauge is the same or larger. A replace wire with smaller wire gauge will warm up like you see.

Thanks for the tips I will check fuses and what is under the tape... maybe some funky connection.

I will keep you guys posted.

More information,

Removing fuses 4 5 or 6 the blower still works.

Only removing the fuse 12 the blower turns off.
Also with ONLY the fuse 12 in his place, and removing 4 5 and 6 the blower still work.

Is this normal? Or I have a short somewhere?

[DaveSmed]

Fuse 12 is supposed to be a 7.5A fused circuit powering some small electronic things like your radio.

Some chucklefuck somewhere along the line decided to wire your blower motor (which should be on fuse 20 FYI, a 30A rated circuit) to the wrong thing.


At least you caught it before the fire.

EDIT: Do NOT run the wipers and blower motor at the same time until it gets fixed!

oh shit

Yes you are right, when I remove the fuse 12, the radio and clock and some other things go off.

I guess I must remove the head to check out the wiring on the switch.

In a "pain in the ass mixed with some pain in the groin" scale.. lets say 0 to 10...this jobs takes wich score?
1? 10? 8412?

[DaveSmed]

Removing the radio and taking a look back there isn't usually TOO bad. It is tight though. If you end up having to remove the center panel, there's a screw in a shitty spot that will prob keep ya busy for a bit.

I also tested my current draw in the system

The meter set up to 10A.
With everything turned off = .21
with 1 light on (inside, trunk or glovebox) = .53

Is this a normal draw?

Dave, I will try to tackle the radio problem tomorrow taking a lot of picks, any help will be appretiated (:

[DaveSmed]

Those numbers should be more like 0.021 A.

Battery going dead if the car sits awhile?

[mgromero]

Yes actually I think that other chucklefuck installed a second battery in the front.

So I have 2 batteries, one in the trunk with the original wiring, and one in the front connected in series.
Removing the battery in the front , and measuring current draw from the back I get those readings.

If I should get a 0.020 reading setting up the meter to 10A .. that means that I still have a draw of 0.19 amps yet! Thats a lot.
I need to pull every damn fuse :P
