Hey everyone, ive got 2 little problems on the supra that need to be sorted, my only problem is, i dont know what the cause could be. Here they are

 

*Auto shifter + speedo cluster illumination

 

*Passenger side headlight fog to be fixed (all other front lights work just fine)

 

I know by law we dont need front fogs, but id like it to work propely. What could be the cause of these 2 problems??

 

Thanks, Kevin

It's normal for some fuses to be "missing" in the fuse box (mine certainly has, other specs may vary): they're just unused slots IIRC. If the bulbs are OK but aren't getting any power (test connections with a voltmeter to confirm), then suspect relays (if there are any in the circuit) or the switch. Not sure how best to track it back other than following the loom from the headlight cluster though.

I reckon it has to be the relay, my dad did some tracing a while back, removed my fuse box to check even further but nothing:(

I don't suppose there is a diagram on how they should be wired?

 

For some reason my front fog wires have been cut and spliced into something else.

Not sure to what as they don't work, but looks like the indicator wires have been changed to.
