CAN ANY ONE HELP ME OUT MY HEATER IS NOT WORKING AND IS BLOWING COLD AIR

 

Have you checked your water in your cooling system? Check header tank is full and run the car with the cap off and the heater on full blast to see if there are any air locks. How old is your anti-freeze? Any frozen points will stop the flow also. Other than that the only thing I can think of is a knackered heater matrix but I have no experience of them. Or thermostat not opening would also stop the water heating up.

Good luck.

 

It's actually more likely that a thermostat STUCK OPEN would cause the water not to get hot.

Are the top and bottom hoses hot when the car is hot?
