so this morning i went out and started the K5 and the heater seemed dead? i was in a hurry, so i just got done looking at it. seems all the wiring, connections, etc are good. took the dash apart and checked the controls on the back of the actual unit thats mounted in the dash. couldnt find anything wrong there? then i noticed that some fluid, looks like coolant is leaking underneath the glove box? what in the hell is that? and could this be the reason my heater is not working? heater core maybe? help CK5, its cold at 4am when i go to work and i need my heat..
