2000 s10

[minivolks]

Hello all,

 

I bought my daughter a 2000 red s10 LS 4 cylinder with 98,000 miles on it. Few dents and scratches but runs great and the A.C. blows nice and cold. I am very handy when it comes to working and diagnosing problems. The used car dealer let me use his lift cause the truck needed a fuel pump, fuel gauge didn't work. I also did some interior work. Under hood the throttle body got a good bath.

 

I would like some help diagnosing why the automatic lights don't come on. The daytime lights work and I can turn them off by pushing the button on head light switch four times. However, when I put my hand over the ambient light sensor the headlights do not come on. I tested the sensor with multimeter and it is responding with the correct values. 5 volts on gray wire and 1.7-4.7 white wire. light state While .2-1.0 on white wire for dark state. I kept sensor plugged in, with key on, and stuck wires with the multi meter leads.

 

I have the haynes manual with schematic of lights. Could be relay, parking brake switch or, this is strange, the schematic shows a wire going to abs, but it ends. No more info on that in book.

 

Regarding parking brake switch, while depressed the light shows up in instrument cluster.

 

So, here I am, a new member. Looking forward to some conversation. Brian
