2014 Edge Limited No Heat

Recommended Posts

Well...they called back yesterday and said even with the new HVAC module, it's blowing intermittent heat. So, as suspected, they are saying the heater core is clogged. I've already paid $430 for replacement of blend door actuators and the HVAC module. They are saying it's going to be an additional $1059. Does that seem about right? Or am I getting bent over a barrel? I know the dash has to come out, so it's time consuming, but if that's what is required to be done, I'm ok with paying that, but hope they aren't taking advantage of me since THEY misdiagnosed the problem after I told them I changed the blend doors and reset the system.

Finally got the car back today!! All said and done, I paid $1523 out the door. That included replacing both blend door actuators (not the problem), replacing the HVAC control module (not the problem), replacing the clogged heater core (not the real problem), and replacement of a valve (real cause of the problem).

 

They had to pull the dash completely apart, and in the process, broke the trim around the touch screen, which is about $500 to replace (at their cost). So, all said and done, the job was about $3k total, but because they misdiagnosed the problem TWICE and had the car for 2 weeks, they gave me a $750 discount, and are covering the $500 broken plastic piece.

 

Long story short, I spoke directly with the technician. Apparently there is a valve connected to a hose that goes into the transmission. If that valve fails, it lets debris into the heater core, which causes it to clog. I'm not really sure of how the design works, but essentially a $100 part fails, which causes a $3k repair. Seems like a bad design to me.

 

All in all, the dealership took care of me when it came to final cost, considering the multiple failed attempts at properly diagnosing the problem, and breaking interior pieces along the way.

For anyone who has this problem in the future, here are the part numbers they replaced:

 

DT4Z19980H: HVAC control module

DG1Z18495A: HVAC heater control solenoid assembly

7T4Z18476A: heater core assembly

VC3B: anti-freeze top off

 

R&R HVAC module, heater core, and trans cooler valve

 

The trans cooler valve, or heater control solenoid assembly, or whatever you want to call it, was the root cause. It was about $100...

Well it's been about 6 weeks and no issues. It sucks that the design flaw of a $100 part causes close to $2,000 in damage repairs. Oh well, my wife loves the car and it's great for traveling, and we own the car, so fixing was the right choice!

 

Plus, they broke the touch screen radio fascia on reinstall, so they replaced that too, which was around $500 I believe! Brand new touch screen control!

Hate when this happens, UGH.

 

Miles on your Edge, history of coolant changes?  Is there slime buildup in the reservoir/degas bottle (bottom half)?  What coolant was in there prior to the heater core being replaced?  Specialty Green, Orange, or other?  What coolant did they replace it with?

 

EDIT:  BTW, while replacing the heater core IS a labor intensive job, it does not require removing the whole dash as in older MYs of other vehicles.  Lots of steps tho:

 

Heater Core And Evaporator Core Housing

As far as the valve, this is likely what they were referring to (and probably where the leak is from due to faulty repair):

Coolant Flow Diagram - 2.0L Gasoline Turbocharged Direct Injection (GTDI) Temperature Control Valve

NOTE: The temperature control valve directs warm coolant to the transmission fluid cooler/warmer mounted on the transmission during transmission warm-up and allows the coolant to bypass the warmer when the transmission fluid reaches normal operating temperature.

NOTE: At 38°C (100°F) ambient temperature, amber arrows indicate temperature approximately 82°C (179°F).

102k currently. Bought it with 72k from the dealership where the original owner traded it in. It belonged to an older lady, and all maintenance was done at the dealership. No slime buildup that I can tell. Orange coolant prior to heater core change. I'm assuming they replaced with the same Ford orange coolant.

So, it is dripping down from the passenger side of the engine, where the pulleys are. That valve you reference is on the other side of the engine, so it's not the issue. Is the water pump on these engines internal?? All I know is that I've NEVER had to even top off the coolant since owning this car for 3 years. But, since getting the car back after the repairs, and less than 100 miles, it has lost almost a gallon of coolant. Something tells me that the repair was not done correctly, or when they reassembled something, they caused damage to something else.

Thankfully the water pumps are external on the ecoboost engines, and cheap to replace as a result.

Removal and Installation

  1. Drain the cooling system. For additional information, refer to Cooling System Draining, Filling and Bleeding in this section
  1. Loosen the 3 coolant pump pulley bolts.
    • To install, tighten to 20 Nm (177 lb-in).
  1. Rotate the accessory drive belt tensioner and detach the accessory drive belt.
    • Make sure the accessory drive belt is positioned so coolant can not contaminate the belt.
  1. Remove the 3 bolts and the coolant pump pulley.
    • To install, do not tighten the bolts at this time.
  1. Remove the 3 bolts, the coolant pump and the O-ring seal.
    • Discard the O-ring seal.
    • To install, lubricate the new O-ring seal with clean engine coolant.
    • To install, tighten to 10 Nm (89 lb-in).
  1. To install, reverse the removal procedure.
  1. Fill and bleed the cooling system.

 

Could be the thermostat housing as well.

Thermostat Housing — 2.0L GTDI

Removal and Installation

NOTE: The thermostat and thermostat housing are replaced as an assembly.

  1. Drain the cooling system.
  1. Release the 2 clamps and disconnect the 2 coolant hoses.
  1. Remove the 3 bolts and the thermostat housing.
    • Inspect the gasket and install a new gasket if necessary.
    • To install, tighten to 10 Nm (89 lb-in).

What temperature for the auto setting?

 

I usually have it set around 70-73 degrees.  Outside temps are below 40.  I just reset the system with the power/defrost buttons and there was no change.  I hear the blower going in auto mode but nothing is coming out the panel vents.  If I switch to panel it blows heat just fine.
