I have a 99 suburban K1500 5.7, and am looking for some help with my daytime running lights. I went out the other day and upon turning on the truck noticed no auto daytime running lights. I have checked the fuse box on the side of the dash, the box under the hood and nothing seems to be blown. I have replaced the headlight relay under the dash with no results. If I manually turn the headlights on I have high beams, but no low beams. I have checked the actual bulbs on the low beams and they are fine. I was told that it could be the daytime running light module, and that it was located under the dash to the right of the steering column. I have ordered the part, looks like a oversized computer chip(which I guess thats what it is), but have yet to replace it Any advice on replaceing the part, not even real sure how to go about it. Am I even looking in the right direction to solve this problem? Any advice/help would be great. Thanks in advance!
