I've got that wiring diagram and even tho it says red/black, There is no red/black wire in the wiring harness going up to the switch on the steering column. The #14 pin in the connecter(where the 2 bundles of wires come together on the steering column)is a red/white wire.

Check the voltage of the wire .. then jumper it to the #4 on the relay ..then does the switch work correctly ??

I believe that wire has 12 volts but I can't check til tomorrow.I blew a fuse and don't have a replacement. I go in the morning and get one and then I'll don the check. Talk to you tomorrow.

Hey Mike

You now have a HOT going to #1 and #3 @ relay because you jumped them ...(see red arrows on diagram) so the fault you now have MUST be on the wire from #4 going (see blue arrow on diagram) to #'s 13 and 14 on the switch or the switch itself is still faulty !!! If you ground out #4 on the relay to the chassis your lights will work all the time ?? they won't be switched !!! you have a permanent live and a permanent ground to the relay !!! let me know

The lights come on when I hooked up #4 to ground with #1&3 connected. When I was checking my pins on the old switch I found the 3rd one over from the end ( I believe it's #12 wire) of the connecter burned as if it had been shorted. So I went out to the car and disconnected the new switch and there was also a burned area on the opposing pin in the connecter going out to the relay box. The color of the wire is red/black. It doesn't appear to have hurt the wire except the plastic around the pin was melted. I never noticed it when I installed the new switch. This may have been the original problem as to why the hi beams weren't working properly. Now I have to decide on a plan to fix the problem. Question- when the HL relay is engaged shouldn't all 4 legs have 12volts on them?

He Mike ... good morning

I'm getting a little confused now (ha) .. you stated 3/4 post's back that there was NO red/black wire going to the switch ? you are now saying you have a burn't red/black wire/pin on switch ?? am I correct in saying we NOW have 12 volts to #1 and #3 and you have a burn't plastic surround on the red/black wire/pin on the SWITCH pin #12 is for ground from HL switch high/flash to pass direct to HL bulbs and could well be the problem !!

When you grounded #4 relay pin direct to chassis .. the switch did not work but the lights came on ... am I correct ??

Also #4 should never be HOT (12 volts) it is the ground from the switch it energizes the relay

#1 = HOT all times (12 volts)
#3 = HOT all times (12 volts)
#4 = 0 volts @ all time's
#2 = 0 volts with light's switched OFF @ switch
#2 = HOT when relay is energized (12 volts) when light are SWITCHED ON at switch

The HOT from #3 and the GROUND from #4 energize the relay when the light switch grounds out #4 sending the power to #2 on the relay

The #12 on the switch GROUNDS the HIGH/FLASH TO PASS bulbs .. hope this helps and iv'e not confused you .. as I said I'm getting a little confused and have to keep going back over the prior post's ..(ha ha) .. let me know

To ground, YES. Terminal 4 may not be a full 12 volts, but you should have + voltage at all 4 terminals.

That's OK Dave I know how easy it is to make a slip and man I appreciate all your input. They say communication or the lack there of causes most of the problems we have and sometimes I'm not the best at it. I didn't realize that there would be 2 different color wires at the connecter and so I was looking at the wires on the switch side of the connecter which is red/yellow but on the relay side of the connecter it's red/black. I'm sorry for the confusion.

I don't normally drive this car my grandaughter does and I was talking to her this morning and she told me they drove the car with the headlights on all the time and when they shut the key off the lights went off, and each time they started the car the lights would automatically come on. So I did some checks using the ign. Switch. With the ign. On and HLswitch off I got 12 volts on all the legs except #2. With the ign. On and the HL switch on I got12 volts on #1, 0 volts on #2, and 8 volts on #3&4.I don't know if that means anything or not.

I'm kinda at a standstill right now. I'm wondering if two wires could be shorted together somewhere between the connecter on the steering column and th JBox. I just can't understand, when the ignition is on and the HL switch is on, why does #3&4 leg show 8 volts. That's the reason the relay isn't kicking in.

Sorry I didn't see your last post before this one .. for some reason I wasn't notified you had replied ?

OK lets try this !! jumper JUST #13 on the switch to #3 on the relay .. this will take out of the equation the itergration relay ???????????

Wait a minute ... did you say you had a YELLOW/RED wire coming from #12 and #13 coming off the switch ?? let me know

I can't believe I didn't check this sooner. Your vehicle IS fitted with DRL (daytime running light's)? The LO headlight's are supposed to be on constantly?

Dave: The #12 wire on the switch side of the connecter is red/yellow. #13 wire on the switch side of the connecter is red. The #14 wire on the switch side of the connecter is red/white. As far as having DRL, I don't think this car has them because we've always been able to turn the lights off when the car is running. Also from looking at my Haynes manual it indicates that only the canadian models had the DRL"s. Did you want me to jump #3 to#13?

Well, we're going to have to back up here a few yards, and punt. Dave and I had a little chat off line and he informed me that we probably were looking at the wrong diagram for your system. I believe he is correct. Of the diagrams I sent you, do the wire colors on the W/DRL diagram match the colors on your system? Please advise.

James: From what I can see the colors don't match up with the DRL schematic and like I said in a previous comment DRL's stay on all the time and mine didn't.

Hey Mike. good morning

OK heres the deal mike, I had a chat with James and we discussed your problem and we looked back over the post's .. and we also re-checked both wiring diagrams, I have even looked the wiring diagram's for the years below 93/94 and above 96/97 and they are all identical ... there are no RED or RED/WHITE wires .. unless you are actually working on the DRL MODULE (see diagrams)and NOT the H/L SWITCH ... Also the DRL module sends the GROUND through a Dimmer Relay ...this would explain the voltage drop you are getting ... Could you possibly supply us with a photo of the switch and connector you keep mentioning .. I do not understand what connector you are talking about ? the #13 wire (red/yellow)should go from switch to intergration relay then change to a red/black wire from relay to relay ..the #14 (red/black) should go directly to #4 on HL relay there should be no connector in between ? let me know your thought's ??

This is a picture of the switch and connecter I marked #'s 12,13,&14.the red/white is the 1st wire#14, the red wire is the 2nd, #13, the 3rd from the right Red/yellow is #12. There are eleven wires in the HL bundle.
