What is the engine temperature? It may be that the thermostat is stuck open and the engine is running cold.It may also be sometheing stuck in one of the lines that moves to block it when the flow starts.

Cool air coming from vents


The two lines are 1. the hot water coming from your radiator and 2 the return water coming out of the heater core going back to the radiator. If the hose is hot which it should be and the return is less hot which it should be, it sounds like you have an issue with the temp controls part inside the vehicle. It is electronic I think so that is more than likely your problem.

Both hoses are hot, heater core not clogged, blend doors work fine (already check via cutting in the assembly for repair), blower works fine, luke warm heat coming out 1999 jeep grand cherokee laredo


ok, its just a heat exchanger.
all that matters for heat is:
1: the engine must reach 180F + and hold, does it.???
we use the scan tool , is ECT reading that, good.!

or hand IR pyro gun,,, pointed at the thermostat housing
then pointed at both heater hoses.... what do they read.

2: the hot water must flow through the core, must.

3: air must flow through said core. (damper or dirt blocking core)

1,2,3.

How can i troubleshoot my heater core


It's just a simple small radiator. Coolant circulates through it, and the cores' fins give off heat that is picked up by the blower motor.
When the engine is at normal operating temperature, feel the two heater hoses. Both should be hot, verifying coolant is circulating through it. If only one is hot, the core may be plugged or have an air block. You can take off the core outlet hose and observe stream flow when engine is running and heater on high heat-flow should be slow but steady. The outlet hose will run from the firewall to the front of the engine into a fitting near the water pump. Some cars have a water valve in one of the hoses-make sure it is open, for coolant to circulate.

If both heater hoses are getting hot, the problem could be a stuck blend door under the dash.
If only one hose is getting hot, there is a blockage in the coolant flow somewhere.

Check if there is a vacumn powered valve in the heater hoses, if there is the vacumn hose may be faulty [ broken or crimped.] or the valve is faulty. good luck.

No heat,hot water is going in the heater core,good


it is the blend door actuator. lol i just did one today since here in Houston we had a little cold snap and everyone is realizing that their heater isn't working. The blend door actuator is on the bottom of the heater case and has one plug with 4 or 5 wires. It requires a 5.5mm socket to remove 3 screws and just pull down to release it. Hope this helps.

No water to heater coil....no heat . replaced thermostat , but no waterflow to heater coil,


6or8? Some of those have a lot of **** in the system. If it has a water valve in the heater lines, make sure it is operating properly. Check to be sure the hoses are hot going in and out of the firewall. This should be checked just as the thermostat opens. You can tell by checking the top hose to the radiator. When if gets hot all at once, check the heater hoses. If one is still not as hot as the other there is no flow. This could be the water valve, if equipped, a restricted core(which you may be able to backflush if careful), or in worst case situations..a blown headgasket will put air in the system and not allow the heatercore to get fluid. Good luck. TJ
