Overheating, AC/heat only works on 4
I bought my 2000 jeep Cherokee sport in 2010. Shortly after the AC and heating controls stopped working at the 1,2,3 settings and only work on 4
Yesterday during/after a 2 hour each way drive the check gauge light comes on and the temp gauge immediately goes full tilt. When I got home the entire contents of the radiator spewed out.
This morning I fill her up. Drive about 12 blocks and I became a roaming smoke screen.
Any thoughts? I'd love to save some cash doing this myself but time involved and cash also decide if I ship this to the mechanic.
