Question about 2000 Ford Explorer

2 Answers

No AC in my 2000 Ford Explorer

Took 2000 Ford Explorer to dealership to replace heat core. I have heat now -- no AC. Note: the AC was working fine before I took the vehicle for service. The technician told me there was a leak. They tried using dye??? but cannot find the leak. I was told to come back when the weather breaks? Don't ask -- I have no idea what that meant or what sense it made. I will be returning to the dealership. More freon was added and tested to insure I had some air before I left that day. Right now no AC. Question: is there a connection between the heat core and the AC? when you are replacing a heat core does the freon need to be drain and the unit removed to get to the heat core. is it any way possible the mechanics could have accidently punctured the AC unit while trying to replace the heat core?

thank you

The cooling system in a car is pretty simple. If you have a clog in a hose or elsewhere you are going to have an overheating problem. The water has to circulate to keep the engine cool (Cool to the engine would burn you). Now we divert some of this water to another radiator inside the dashboard and blow air across it ... voila Heater! That said if you put your heater on defrost and you get steam on the windshield you have a leak in the Heater Core (radiator in the dash) or in the AC .You lack of COLD can be caused by 2 things 1. No hot water in the heater core ( most cars have a bypass if this becomes clogged so that you don't blow up the engine) 2. The heater vent controls are not working correctly. Make sure that when you change the control setting that the air flow changes correctly. There is a flap in the heater box that changes from heat to A/C. If that is not working correctly it may stay on heater core all the time. If it is the hose and heater core clogged back flush the heater core. If you do this replace the heater hoses. I would also verify that the thermostat is there, installed correctly or may be its faulty, and its blocking the AC to get started. Flush and thermostat are do-able.
also Check operation of radiator fan. A partially plugged radiator may be causing your problem. Replace radiator with new, and your heater core may be partially plugged also.
------------------------
and yes for your question ,that while replacing heater core ac unit is also have to be removed
as this is the procedure

5. Remove four heater core access cover retaining screws and remove heater core cover (18B300) from A/C evaporator housing.

Yes dear there is connection between heat core and AC.well yes AC might have been punctured accidently as it needs only a small leak to damage the AC.The gas just continues to leak out of it.Always take care that ur AC is never get any kind of leakage and and please dont clean ur AC with acid as it causes corrosion and gas leaks slowly slowly.
And one more thing try to get it done by a perfect mechanic.

Thanks!
Sandy

Have a 2000 ford explorer v8 and when i try to turn the ac on it wouldnt tryed the heat and its the same thing but the weird part is that it comes on in the back do you know what could be the problem


You most likely have a problem with the door that diverts air either over the cold AC evaporator core or the over the heater core, it is called the blend door, it is a common issue in the Explorer along with the AC condenser leaking (in front of radiator). to repair it you must remove the entire dash assembly for access. I assume that the compressor is running when you have the AC on but no cold air is coming out the dash vents? Let me know if that is not the case and I can assist more, was a Ford dealer technician for 25 years and did 100's of these..

My ford explorer only blows heat when turned all the way up


Sway bars are there to give cornering stability when steering and as such is a safety requirement. The link will be cheap and easy to replace so why waste time and risk safety to put it off. As to the heating problem and I would be checking the control module that allows the heater tap to turn on as it appears that there is insufficient coolant getting into the heater either from a tap half on or blocked hoses/core.

2005 ford explorer heat dosnt work


pull back the carpet on the passenger side and check for moisture, if it is wet your heatercore is bad. if no moisture and both hoses going to your heater core are hot it is possible the cable operated door is failing to open. this link should help in both cases http://www.autozone.com/autozone/repairguides/Lincoln-Aviator-Ford-Explorer-Exp-Sport-Exp-Sport-Trac-Mercury-Mountaineer-2000-2005/Heater-Core/Removal-Installation/_/P-0996b43f802e40b6

When i turn the heat on it makes a clicking sound, and it blows out cold air, but when i turn cold temp on the clicking sound stops, until heat temp is turned back on. please tell me how to fix this...


Your ac blend door is broken or the actuator that opens and closes the door is broken. The ac blend door moves up and down to direct air flow through the heater core(for heating) or evaporator core(for cooling).

When the door mechanism breaks, the blend door falls down and you will only have ac but no heating.

You can buy a ac blend door kit for your explorer, they cost about $120 on ebay or other places.
search for Explorer ac blend door kit.

The duct is under the the dash on the drivers side. And you will have to cut open the duct to install the replacement door.

Heres a link to a tutorial of how to do the job.

Heater hot/cold control knob doesn't work need to have the hot air.


Check the motor on the top of the heater plenum. It turns a shaft to shift the blender door which controls the input to this plenum either the heater core or the evaporator core (ac). You may find the motor is OK but the shaft (plastic) has broken and the blender door has to be replaced. This is a costly job that involves removing this plenum after removing the dash. A shortcut I found online was to cut a hole under the blender door and replace it through this opening. After replacing you can seal up the hole with epoxy. I cut three sides of a square hole leaving the back uncut. Pull down and the blender door can be removed. My problem was on a 1997 Explorer. _6.gif

HVAC reduced Air Flow


You need to clean the front of the AC evaporator core, they get plugged with leaves dirt etc., have even see bags stuck to them.
