Cold air coming from rear vent of 2000 mazda mpv

Hello I have a mazda 2000 mpv EX with front and rear heater controls. I noticed water leaking from underneath the vehicle beside the spare tire. After investigating i realized that a pipe that carries the coolant to the rear corroded and broke. I cut out the rotted piece of the pipe and replace it with a piece of heater hose I get from the scrap yard. I top up the coolant reservoir in the engine compartment. Everything is fine, plenty of heat from the front ventilation but the rear has no heat. The fan at the rear is working because the air is coming out but it is cold. Please help!! Thank you.

Check heater pipes under the vehicle, as these have heater controls in the back of the car the pipes rust out causing coolant to leak out. cut the pipes and bridge them together as you dont require a heater in the rear of the vehicle. Costly if you cook the engine if its a V6, as you have to pull the engine out to do head gasket replacement.

2004 Mazda MPV cabin air is just not getting hot enough.


If changing the thermostat didn't work, have the heater control valve checked, it may not be opening all the way to let the coolant circulate thru the heater core fully.

The heater lines that run to the back of the right rear side gets rusty and start to leak anti-freeze. There is a black cover under and above the RR tire that has to be removed so u can see.
