heater malfunction????
I got the car to run after it was sitting for 2 years. The heater was working perfectly fine until 2 days ago. i checked the fuse and reset the heater relay. Still didn't fix it. I think the heater core is clogged. How do i unclog it??? What do you guys think caused the problem?
thanks...
thanks...

i tried every method possible: i took one of the hose off and let the engine run, used the flush kit, still doesn't work. Fuse is fine. I will have to replace the heater core or make the plate open all the time. Would the 1990 heater core wiring plugs be the same as the 1987???
