are these related?

oil pressure gague

Heater fan

I was just coming home and these things all just shut off on me....in the rain...all at once.

I have no clue????? just replaced tumbler and headlight switch.

Tons of problems all at once#*%#-#+$-%

Yep, they all related in the sense that they are all electrical, needing a complete circuit positive to neg to work.

I'd start with checking grounds. Battery, especially engine to body.

[STERLING STINGER]

Cool I'm actually learning. :) Other than the battery and the drivers tail light, doea anyone know where any others are?

 

I'm really leaning toward it being something with the ignition, or it being in park all the way, or something incredibly hard.....but grounds first

[Pete M]

I had to run a new ground to the dash in my 88. everything worked better afterwords. :D

[STERLING STINGER]

Where is it by the dash Pete? do u know where all the grounds arw located?

[64 Cheyenne]

Sometimes the ground strap from the block to firewall can be the culprit, especially if it is mucked up.

Jeep ran the chassis ground through the block then to the firewall. Bad idea.

Some guys run a separate chassis ground from the battery to the fender, circumventing the block to chassis ground. Be aware you still need that ground though (engine).

[Pete M]

I'm not sure where the factory one is. I ran a new wire from the battery to the metal part of the dash above the drives feet. If I remember right, I was having trouble right after installing an aftermarket radio (which was asking for lots more juice).

Ok thanks ill look

Another thing to check, turn heater fan on, check for voltage at the heater motor. If you have voltage, then probably a ground issue, no voltage, then power supply issue.

 

You can unplug the heater motor at the bulkhead (under the pressure bottle if Renix) to check for voltage.

K ill look thanks

Do your horn and radio still work? If not, I had similar issue on my XJ (no horn, wipers, radio, heat/fan control) and it turned out to be a fried ignition switch (among a LOT of unneeded wires from PO :headpop: ).

Isnt that the white box the tumbler shaft goes into?

[beaterjeep]

No, the ignition switch is down lower on the column. Towards the firewall, pretty much on top of the shaft. Mine had a blue connector going into it, with I think it was 5-6 wires coming off of it. HTH.
