My '97 Tahoe is having a starting issue. It is acting like a dead battery. It first happened last night at thegas station, i had to have it jumped. After that it started maybe a half a dozen time last night. This morning I had to put the charger on it for it to start. I probably started a dozen times today with no issues. Tonight it did it again. Chrged it, drove it to O'Reillys and they checked the battery, charging and starter. Everything check okay. I noticed coming home yesterday and today a clicking sound coming from the left kick panel - glove box area. Is there any relays around there that would control the battery - charging system?
