The other night i was driving home at about midnight after my hockey game and my heater was blowing out nice hot air. I ended up turning it down because it was too hot. The next morning i went out to start my car and let the engine warm up. When i got in the car and turned the heater on for my drive to work it will only blow cool air.

Any ideas as to why? Please help it is cold where i live and i would like to have some heat in my ride.
i drive a 95 Disco with a 5 speed tranny.

 

Sure, you have a coolant leak and now have air in the coolant system. When have you last checked/filled and bled the coolant system?

 

+1 find your leak and in the mean time make sure your coolant is topped of or you will overheat and possible kill your engine. Keep a close eye on your coolant temp.

 

worst is that it is cold but no snow! I want to try my darling in snow now! Puhleees!

 

When you add coolant you should bleed it also.

 

Yes, cold, tonight it is supposed to be 0 degrees out, been snowing on and off all day and tomorrow too. Turn on those seat heaters.

 

sadly not here, here is 9, rainy mostly and my car looks like mud ball. They already hate me in hand wash street.
Seat heaters check
Heated windows, front, rear, check

I am ready!
