My dad has a 1998 Cadillac Catera. He has three queations about problems he is having.
1. Everytime we open the engine oil fill, there is a a layer of milk-like substance, kind of like when oil and water mix, but there is no water in the oil. What could this be?
Someone suggested pcv, but I know we do not have a pcv. Any ideas?
2. When we turn on the heater, only the drivers side warms up but the passengers side doesnt even though both climate controls are set to hot.
3. Temp gauge does not work properly. We have changed the Coolant temp sensor and the gauge sensor but still doesnt work. Ideas?
Thanks in advanced,
Mike
