Answer
Walter,

No heat in your cabin sounds like you may possibly have a bad heater core. Also white smoke coming from the exhaust is indicative of a blown head gasket. You will need to take your vehicle to a reputable and trusted mechanic as you will need to have the head checked to make sure it is not warped. This could be the reason your vehicle is running hotter than normal. Hope that this helps and if you need further assistance, please do not hesitate to contact me. Good luck.
