Trying to get my heater working

[cerberusaardvark]

Awhile ago my heater started working erratically. Eventually it just went out. I've replaced the heater core, heater hoses, blower motor and blower motor resistor but it still won't turn 9n. How can I troubleshoot fro here?

On a side note, my ac compressor is deleted and there's a hole is the side of the ac box where I broke it to get a head jolt torqued down

How about the relay?

You mean the fan won't blow or just cold air?

mine never worked but the mechanic i was with ( my father) just put a golf tee in one of the hoses he said that it helps the water continuously flow. if you would like a pic of it i could grab one for you haha.

I'm on my third "heater" relay and was about to buy the forth when I noticed that my blower came on when I wiggled the relay. Hmm! Turns out the connection was dirty from a previous spark. I cleaned the existing relay with sand paper and all is well.
Best of luck!
