No heat at idle could be a failed aux pump.
No heat at anytime could be -
1. Air in the cooling system. On gen I that is usually due to a cracked degas tank. (They crack just as much on gen II, but gen II has other parts that crack a lot too.)
2. The filter screen in the upper radiator hose where it tees off to the DCCV is clogged.
3. The DCCV is clogged or stuck closed.
4. The cold-air bypass door is stuck at the bypass position (you should have gotten a fault code for this).
