I have a 1989 GMC S15 Do you have any videos that are close to showing how
to replace the dash lights I can hardly see how fast I am going at night.
Thank you for posting your how to vids.
You may want to check the fuses.
@Badboy4you1911 No problem bud, anytime.
i have a problem. I have a 2003 2500HD silverado. Duramax/Allison with 137k
miles now. Just yesterday for no reason service 4WD came on when I was
driving through town in 2wd. It will not go into 4wd, the lights that light
up 2hi, 4hi, and 4lo are on but the lights right to the left of the
switches, the little round yellow ones that show which mode you are in are
not coming on at all, all are off, and the red neutral one is not on
either..Any suggestions?
@JHONSONAREA51 You may want to check the actuator to see if it’s
working.Hope this helps.
help me ! when i press low bottom tilt tilt but not keep on what could be
the problem?
I have 94 s10. When i press either 4wd button, both lights will flash and
there is a clicking from under the dash but it wont engage into 4×4.
Sometimes both lights will stay solid, and other times both lights will go
off and the 2wd light comes back on. Any advice?
it’s not for headlights….. 4×4 switch don’t have light on 🙁
yes, everything works good….. could it be the transfer case module?
@1aauto thanks tony
@1aauto I removed the grill and headlight, then you can see the accuator.
when i hit 4wd the accuator sucked in slightly then slowly released, when i
hit 2wd it would suck in all the way and stayed in. it was the vaccum
switch on top of the Tcase. the ball was sticking on the switch. I replaced
it and now it works great…… thanks for the help
You may want to check the switch and also the actuator to see if it’s
working correctly.
If the headlights are not working, it might be a bad headlight switch.
will this trick work on 1996 chev s10
You may want to check the vacuum actuator to see if it’s working correctly,
it’s common for them to stick and stop working correctly with age. We carry
new ones on our website 1aauto.com if that’s what’s causing the issue.

ohh ok tanxs so much. 🙂
My selector switch from 2h will not blink when I switch to 4 hi I and will
not go into 4 wheel haha I but if I put it in neutral
thanks u the best…
@allhunting Hmmm…Have you checked the hubs themselves to see if anything
is worn in them causing them not to stay engaged. We also sell the vacuum
solenoid, but usually if that’s bad the dash light will blink (you said
yours stays lit). Here’s a link to that solenoid on our website if you want
to see what it looks like.

@allhunting This is also true. If you have any broke,brittle or dry rotted
vacuum lines under the hood of the truck, you should fix them as this could
also resolve the issue that you are experiencing.
my problem is the “dash light’ I replace the bulbs, check the fuse, replace
the dashboard, check the wires, what else can i do… please help…. and
thanks good videos…. solismateo82@yahoo.com
I have a 1999 Chevy blazer and I’m stuck on 4lo will switching the switch
fix the problem?
