Heater not heating
OK, fun stuff heating systems in German cars....anywho, our '94 Golf has not had a very good heater ever really, and it slowly got less and less warm. However, the heater core started leaking and, after much prayer and wringing on the hands, we replaced it. When I had the box out, I vacuumed out all of the typical MK3 foam debris from everywhere I could. Upon the reinstall (no leaks: yay!) the heat wasn't making muster even though the engine side hoses clearly indicated heat transfer to the core.
Any ideas on why this is? If I have to pull the HVAC box again, I might not live through it: frustrating endeavor to say the least; I much rather rebuild the engine!
