1997 Chev Tahoe Other - Electrical & Lighting Systems
Question: The daytime running lights on my '97 Tahoe were disabled by the prior owner (I assume). How do I correct this? The daytime running light indicator on the instrument panel works as it should, that is, during the period when the headlight switch is in the off position, which would indicate that the daytime lights should be on.

Technican: Do you have an Owner's Manual that lists the Fuse and Relay locations and purpose?
It could be as simple as burned out bulbs, or a relay removed. Remove one of the lights and check for voltage at it's connector when the key is ON and your DTRL indicator is lit-up. Do you have voltage?
Please advise.
Owner: I'll check, but everything works except the daytime running lights which are, in effect, the headlamps which function properly when the switch is on.
Technican: Okay, I'll get a wiring schematic tomorrow and see what suggestion would help.
If the DTRLs are indeed the headlamps themselves, then a relay or fuse could easily be at fault because the voltage would be split from one feed, and put the lamps in series. Wired in series causes the headlamps to come on at half power/brightness.
Do you want me to FAX what I find?
Technican: Do you have Quad Headlamps, or Sealed Beam Headlamps?
If you have a FAX number I can send you schematic and graphic maping for the Convenience Center. Would a FAX need a cover sheet?
Please advise.
Technican: Hello, I'm trying to help you. Is this question still active?
Owner: Quad Headlamps. Fax (304) 743-8099. No cover needed.
Thank you.
Technican: A FAX has been sent. My source is The Mitchell 1 Auto Repair Data Base.
The DTRL Module is stated to be found under the left side of the dash and is taped to the wiring harness. Here's How To Get Guaranteed Solutions In Minutes
