No Park Lamps when Headlight On
My Blazer is a 70 with a 67 front clip. It didn't come with the back part of the grille or parking lamps, so I've never had front turn signals. Since I bought it I have installed a Painless wiring kit, new headlight switch and now have the complete front grille with parking lamps.
The blinking functions work just fine (turns and hazards), but the parking lights only turn on when the light switch is on park lights and turn off when the headlights come on. I've read this is a function with the 67-68's, but they stay on with 69-72's. Is there something I can do to make the parking lights stay on when the headlights are on?

Re: No Park Lamps when Headlight On
First thing I would do is to verify that power is present at the park lights wire with the headlights on, it's possible you have the wrong light switch, ground fault or wiring error, Is it a single or dual filament bulb? the wiring is different for each.
the diagram is for a 70-72

Re: No Park Lamps when Headlight On
Thanks, fixit-p. The bulbs are dual fillaments. With the headlight switch on park, the low fillament lights up, and when they blink, the bright fillament lights up. This leads me to believe the wiring is correct and grounds are fine, but I could be wrong so I'll still check the power when I get home. The signals also work fine with the headlights on.
You said the switch could be wrong...are they different from 67-72?

Re: No Park Lamps when Headlight On
I believe the first year for "full time" parking lights was 68. You MAY have an incorrect switch, but even if you do, there is no need to replace it. The cheapest fix is to connect the parking light wire to the tail light terminal on the switch, or put a jumper across the two terminals.

Re: No Park Lamps when Headlight On
do the tail lights go out when the headlights are on?
Did you order a harness for 67? |

Re: No Park Lamps when Headlight On
So I checked power at the light, and once the headlights are on, there's no power.
Quote:
The kit I used was P/N 10206. It says on their website they are 18 Circuts for 1967-1972 Trucks. I don't see one on their website for 67 only, so I don't believe so. Quote:
On the switch, this is where they are located: So, on the pig tail of the light switch, do I simply just shove a wire across from the 927 wire to the 929? Well, first I should probably check to see if there's power at the 927 wire with the headlights on...

Re: No Park Lamps when Headlight On
The terminal where 927 originates is pre 68 park lights the newer switches didn't have that terminal it's possible that the after-market switches have them so the switch can correctly cover more years you could jump it like raycow suggests or relocate the wire to the terminal next to #929 (dotted line) those 2 terminals (3 & 5) are already bussed together either way works.

Re: No Park Lamps when Headlight On
I bought the same kit... for our 69 and have the same problem, so I'm glad you asked this question!

Re: No Park Lamps when Headlight On
Man I love this site. Installed my new parking lights on my '67 and they turn off when the headlights come on. Instead of starting to troubleshoot under the hood and dash I search my problem here and found this thread. Saved me hours probably since I suck at electrical issues.

Re: No Park Lamps when Headlight On
Yes probably normal. Was it identified as a problem in this thread that the parking lights don't glow with headlights on?
