Blocked heater core. Common as on cars of this era. Massive anus of a job to fix properly (removing and replacing heater core = most of dash out). Poor mans fix - disconnect the hoses at the firewall, connect garden hose via barb fittings, give it heaps.

I have a seen a few car vids of guys using compressed air to help unblock the core also. The trick is to work out which way the water normally flows and then connect the hose or air the opposite way to the normal flow. The idea is that it helps free the blockage more effectively this way. The other thing I have heard used is bleach and letting it sit in the core for a few hours to help desolve the crap. Mines blocked in my car also so i am going to have a go at freeing it but I think once the cores bad its going to be hard to return the flow to normal again over the long term.

I managed to unblock mine and its working good now, I just used a garden hose and some connectors and flushed it in both directions. I do have the water gurgling behind the dash sound now though. I also had a play with a bypass T junction but its not as simple as it sounds because you need to be careful where you t into the pipes as the TMIC takes up a lot of room above and around the pipes.

I am going to add a smaller T back in as it remove's the gurgling noise but I still want heat so i think that's maybe the best way to go unless your game to replace the heater core.
