I can get heat, but not much. the heater flaps work, switching from hot to cold does just that. AC doesn't heat up much, but the compressor works and it switches from hot to cold - ish on both accounts. Needs a re-gas. Am thinking it needs the system flushing to clear the core, or maybe the pollen filter is ancient and blocking the flow as it seems a little weak even on max fan.
Any offers on a solution, guys?
