What is the problem when the DRLs are not working on a 1999 Chevy Tahoe but the dash light indicates that they are on?
The relay under the dash is either disconnected (a lot of people do this) or it isn't working.
1996 Chevy Tahoe Airbag light came on indicating an electrical problem What where do you need to check to troubleshoot?
99 Chevy Tahoe none of the left rear lights work replaced the circuit board and bulbs and they still don't work How should I troubleshoot?
YES The above answer is right. But the problem is that you will have to change the 97 computer,fuel pump, Engine and transmission wireing harness. You will also have to put the 700R4 transmission in that 97 Tahoe. Reason being is that the 91 computer that you HAVE to use won't shift the 4L60E that's in the Tahoe now. Your best bet is to put a VORTEC back in the Tahoe.
