I have 2 qestions

[jj99yukon]

ok first off. i just got a 99 Yukon SLE and i was wondering if theres anyway to cut off or disable the day time running lights?

and for the next question. theres is a little "sqeaking" form my engine bay while im driving. it doesnt get louder or faster as the rpms get higher and it doesnt do it much at idel. im just wonder if anyone else has had this happen and if so what could it be. i was think the tenstioner pully but like i said it doesnt get any faster.

ok if anyone can help me with either one of these questions, thanks.

later
jj

nevermind the DTRL. i got it.

if the noise doesn't get faster as you rev it up its not a pully. check your fan clutch. i had to replace one on my 96 that was squeaking. try to spin it when the trucks not running.

i replaced the tensioner pulley and altinator before we figured out it was the fan clutch. i still have a slight squeak, may be the top pulley between the altinator and airconditioner pump.

fan clutch put me back about $75.

 

[jj99yukon]

Thanks for the help man.

If it was the tensioner assembly you should be able to hear it chirping at idle especially with the hood up.

They're cheap (around $30 at NAPA) and only takes a minute or two to replace.

from the manuel
How do I turn off the Automatic Headlamp System and Daytime Running Lamps when necessary?


Turn the ignition to RUN.
Press the DOME OVERRIDE button four times within six seconds.
After the fourth press of the button, a chime will sound informing you the system is off. The system will revert back to the automatic mode when the ignition is turned off and on again.

dont complete the cycle I.e if the button clickes you have not done it right, dont push in then push out. push in and only come back far enough as not to turn the dome override OFF again.

oh ok. i think i got it. ill go try it and if it doesnt work ill post again. thanks man.

 

[jj99yukon]

ok i tried it and it still didnt work. ill try it again. some other time. or have someone else try it. let me get this straight. you push in the dome override button to the on position which turns the dome lights off. then hit it 3 times or 4 times? all within 6 seconds. but in the on position dont push so itll pop back out, right? sorry im not gettin right away. so thanks for bareing with me.

quickest and easiest way to disable the DTRL's is to push your parking brake pedal JUUUUST enough for the park brake light to come on...and your DTRL's will go off

 

[blk87brd]

Any chance your speedo is in K's? Canadian models won't allow DTRL's to be disabled, unless you do as fck55mph suggests, use the park brakepedal.

wow I never heard that before of using the override knob and push button to dissable the drl would this steps also work for my 1996 chevrolet tahoe help

 

[serge12345]

how can I get my daytime running lamps working again I checked fuses relays nothing or what did I missed help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[96ProCompTahoe]

how did you get them to go off? if you used the button trick, its supposed to "undo" itself when you shut the truck off and restart it.

if you used the brake, release the brake.

If its something else, post it up.

 

[serge12345]

96pro nice truck I also have a two door tahoe its a 96 too, anyways yeah I cant get my daytime running lamps to work the brake is not apply I changed a relay above the brake pedal also checked fuse 15 on the side of the dashboard also check the light fuse under the hood they worked perfect anyideas im lost

My Yukon set for almost two years, i have always had headlight switch problems i've replaced the thing 3 times.. and now my DTRL are off.. and wont come back on at all, the light in the dash is on... but as for the lights themself... they are off - doesn't bother me much.. but.. what does bother me is my bright light light in the guage cluster will not come on at all.. the bright lights work fine.. but the light wont come on

 

[serge12345]

good question but I have no idea what could be your problem by any chance the thing you change 3 times was it the diode above the gas pedal it has fines and is black in color if this was your problem where did you purchase it I went to my local salvage yard and they had for 50 dollars thats crazy any ideas where can I find for a cheaper price
