Help to heat please

[sparkyaj]

My recent 2.4 heater works a treat in the front. Yet the back one stays cold all the time. Blower is working fine.

COuld this be a plumbing problem or just electrical?

The heater pipes that run to the rear heater silt up and stop the coolant flow to the rear . But first check the valve in the rear is not stuck shut , if it is OK you need to clear the pipes . Someone posted a thread saying they used the brake cable off their childs bike in a drill to clear the pipes .
Remember to refit the brake cable afterwoods
