I just bought a 2002 Honda Accord EX V6 Coupe off of an Auction, It was a flood car that didnt start, I brought it home and changed the ignition coils and it started right up, the car was submerged with the engine cuz the oil and the tranny fluid both had water in it that i had to flush out. Now this is a problem i cant seem to fix. The heat dont work in the car, its always blowing cold air even when the engine and the radiator heats up. I checked the radiator fluid and its full.

I thought maybe its the electronic climate controls that busted and arent working right and not opening the heater core valve so. I checked the Heater core control valve, and opened the valve manually to let the radiator fluid into the heater core and it still blows cold air, i checked all the heater fuses and there all good. I disconnected both lines from the heater core and blew thru them to make sure the heater core is not clogged and it was not it blew all the fluid out of the heater core without a problem.

I dont know what els it could be? Can anyone with more experince help me out what els i can check or what this could be?

Can it be my electronic climate controls? do they operate the flange that opens the vent for the air to pass thru the heater core? cuz they were exposed to water during the flood.

Please help, i live in minnesota and winter is very cold here

Thank you.

 

being a flood car it will be hard to diagnosis this problem down to 1 problem, good place to start is a haynes manual making sure your getting electricity and everything tests out for the componets required.
