my wife just called me, she is driving the 99 tahoe (LT 4x4) saying hi honey, there is something wrong with the car, I asked what it is. she says the steering is getting hard, the engine temp is very high, the battery is low. I told her to park and shut off the engine right away. then she says she hear some noise (after engine is off) something like click click click... I am 30 miles away taking care of my 2 years old, I cant get there until she comes back (she'll have to take a cab...) because I have a old wrangler without doors/tops so no way I can put the baby in this thing... I have to try and fix this thing today... I am thinking that maybe the alternator is on its way out which will explain the gauges going crazy. but not sure about the hard steering and noises she heard after turning the engine off. what do you guys think ?
