Heater Core / Electrical Problems (2.3 Sleeper posting)

Okay, so I paid to have the heater core done. Before I went in, my
blinkers worked. Now they don't. The fuse was replaced, and we replaced
the combo switch as well. Still no blinkers. The hazards do work.

The steering column was dropped straight down, and the right side of
the dash was pulled out. The shop is thinking maybe a ground has come
loose somewhere. Or possibly they pinched a wire.

My question is: Where does the blinker switch ground out? Or how does
it ground out? I would like to fix this myself before having to drop
the car off again for a full day next week.

If I turn my hazards on, then use my turn signal, no matter which way I
select (right or left) the hazards quit working and only the left
blinker flashes. This is very strange.

Any help would be appreciated.

There is no ground for blinkers. The turn signal stalk completes the
12v to either right or left blinkers, and the amount of amperage draw
determines the on-of rate throught the flasher unit. This is why
blinker speed up when one of the bubs is out. The only grounds are at
the lights themselves.

The 12v feed up to the column switch has been severed somehow.

The blinker flasher is usually in a clip. The connector may have
pulled out of it when the coulmn was dropped.

A block diagram would be:

bat->link->ign sw->fuse #5->T/S flash->hazz sw->multi-funct sw->lamps-->gnd.

You may have a power feed or connection issue. Verify fuse #5 is hot by
checking the back-up lamps. Do they illuminate???

The flasher was replaced, which would mean that it isn't unplugged.

All of the fuses checked good. We went back through the entire fuse box
and checked each one thinking maybe something else could be messed up.

Now, when I first got the car back, the horn and cruise control (same
circuit) where not working also. That fixed with a fuse change and
hasn't messed up yet.

I will verify again when I get home, but I think I will be wasting my
time.

I will tear back into it tomorrow. I was kinda leaning on a wire
getting pinched or something. At first, I thought something had to be
wrong because the hazards still worked, but then I remembered they each
have their own flasher and are independent of each other.

I will check tomorrow and see what I can find. Should I pull the combo
switch, disconnect each plug and follow each wire individually? Any
known areas where something might get pinched routinely on one of these
jobs?

Thanks,

Sounds like the power distribution is set up differently between Fox
years, not surprisingly. What does fuse position #5 power???

Start with something easy. Verify 12 volt power at the T/S flasher input
with a voltmeter or test lamp. Ignition switch should be in the run
position. You can work with the diagram flow mentioned in my other post. I
could give wire color codes, but they may differ between model years.
Another thing would be to remove and short the T/S flasher connector with
a jumper, place the multifunction switch to left or right position, and
with the ignition switch to run, verify the right/left indicator lamp on
the instrument panal to illuminate. Depending on the outcome, you'll know
whether the fault is up or down stream and go from there...
