What year is the Blazer?hello, I am having trouble when I turn, feels like I have a flat tire and its stuck or skipping. I just spent a 1000.00 replacing the radiator, fan clutch, water pump and thermostat, i really can't afford another issue right now. The awd service light is on, i know that could be an issue. I need to know what to look for or do to narrow the problem down. Im scared to drive it right now and I have heart surgery coming up so I have a lot of appointments I have to get to. Please help
