Light won’t turn off

Hi Billy, it's possible you have a bad relay in your system. Find the relay that governs the headlights and pull it when you have the headlights on. 

The contacts within the relay could've welded together or the possibly collapsed and as such are still making contact.

It can also be a defective stalk.

The air is also coming out of the vents.

OK. Has anyone done any electrical work to it recently ?? Are you saying that the blower and the headlights stay on even with the key off on the ignition ??

It could be a dodgy switch on the climate control too. Just go through the process of elimination.

Sounds like more electrical gremlins. Start with the simpler things first, like the relays. The relay box, I presume in your Hilux, would be in the engine bay somewhere ?? 
I'm not too familiar with the layout of your particular model. It could also be inside under the driver or passenger footwell area just under the dash.

Perhaps other Hilux owners of the same vintage can chime in.

Toyotas are switched to earth if you get a test light it will light up in the off pos 

get a wiring diagrahm   relay 4 pin ,terminal is 86 high beam red/yellow trace at back of h/light

                                       terminal 30 is +12 volt fused from power souce /battery

                                      terminal   85  is to the switch red wire on back of h/light

                                      terminal 87 is to spotties  that are Earthed =-

     Get an adaptor will have the wires you need already fitted saves having to splice into the original loom that connects to the back of the light and the original connect fitting plugs to it  Kings supply them in the harness called a piggy back adaptor for H4 lights  also available on ebay , 

     Have you just fitted lights or the prob has just developed ?
