I am currently having some issues with both of my vehicles! I just bought a 99 suburban 133k miles from a dealership, got a good price for it in my opinion. It reaks like coolant and the heat is starting to fade away slowly im guessing it is the heater core (correct me if im wrong) the overflow was empty. I noticed it this morning and on the way home from work started getting cold air when the heat was on. no wet spots on the floor at all The 4WD button light sometimes turns off no matter if its in 2hi auto or 4hi\lo the steering feels like there is a hard spot in it and when driving around turns it seems like it goes to being lose sort of jerking a little in the direction im turning. the steering problem is really hard to describe it doesnt feel like the alignment is out at all or that bad. My 99 Silverado 4.3 is having almost the same issue the water pump is going out and leaking. im writing this because of my lack of time due to being a truck driver, and the amount of inconvienence this is causing me plus this rant is helping me cope with the problems that seem to be hitting me all at once. I have an appointment for warranty work on Monday which is still a good ways away. comments or suggestions about the suburban issues?
