You could also pull the hose off the bottom of the condensor box and put a cable tie up into it to clear it and pull the rubber drain hose right out and make sure its 100% clear. Dont stick any metal wire up there as you could do damage. Another way to check if its the heater core or not is bypass it in the engine bay and that will confirm 100% as to wether its the core or not. Also not sure if your aware or not the 80 series had a rust trap on either side up against the fire wall. There is a rubber grommet that allows water in but cant let the water out. It rusts from the fire wall back into the cabin which then lets water into the vehicle. These grommets are visible from under the vehicle just behind the front wheels. If you lay on your back and look straight up you will see them. Pluck them out with a screw driver and leave them out, Someone on hear might have picks of the area. If rusted through is a major job to replate. Probably not your problem but worth removing the grommets anyway if you havnt already. Regards Steve M
