Under the hood there are two heater hoses going into the heater core,with engine good and warm,both heater hoses should be hot to touch,if only one is hot,and the other is cool to warm,then remove both heater hoses,nad flush the heater core out with a water hose.

Only warm air comes out of heater on 89 cutlass ciera core blew out, new thermostat what controls air temp in heater system. Lever moves from cold to hot easily but can't tell if it moves anything under...


#1 Listen if you hear the blend door flap open and close if you do then working good.

#2 run car to normal temp and touch both heater hoses and make sure temp is similar if one is hot and the other warm then your heater core is clogged and most likely that can be the problem it build lime from having tap or well water in coolant system distilled water is recommended but who uses that.

#3 run car when cold with cap off @ 2k rpm and top off radiator. Then close cap and continue to rev @2k until normal temp if heater hoses are not equal in temp heater core clogged.

How to diagnose sound system lost all low en 03 town car


What makes you think its the Heater Core? I just did mine in a 1995 Town car, took 7 hrs with union breaks (lol) You have to take the instrument panel away from the firewall, once that is done it takes 10 minutes to change the heater core. Does your windshield fog up? Do you see anti freeze on the passenger side floor? Do you smell anti freeze? Take the 2 hoses off the heater core, look to see if its clogged, if its clogged, put your garden hose on the inlet of the heater core and let it flush.

P.S The shops will tell you they need to e vac your AC NOT TRUE! they want to get you for another 3 hrs.

How do i tell if my water pump has gone bad


If the water pump was bad, the engine would be over heating. If the engine temp is normal, then the heater core could be clogged or the valve that opens the water flow to the heater core is not opening. You should be able to see if the valve is opening.

Heater core is clogged, not hot heat coming out.


you can try to flush it out by removing both heater hose going into the core and coming from the core. Hook a garden hose to the hose going in and then try flushing the hose going out. Normally once a heater core is clogged there is only the option of replacing it.
