Defrost relay is about $95.00
Damper control cost between $50 to $70
Air conditioner transformer costs between $80 to $100
Labor is negotiable, and its should been between $15 to $20, this depends on the laborer.

Good luck.

bad HVAC, heating and air conditioning system.
Those are damper controls.

be it (vacuum , cable or electric)
2: commands not reaching dampers.
3: stuck damper, or damper bad, bad sevor, or damper motor.
or if cable the cable fell off.
some cars use all 3 damper types. Vac, cable, electric motors.

get it serviced, or get the FSM and read the HVAC chapter.

its has 3 damper motors , all electric and expensive and hard to test
in the TOy dealer they can SCAN it and cycle parts by hand,.

What should it cost to replace a heater core in a 1997 Land Cruiser

varies by series and what is used in your country, HVAC setups are not a world wide constant , nor are parts costs or labor.
why not diagnosis it.??????
1: is engine coolant NOT at 180F, (scan it or pyro gun it) dead simple
if car has a core water valve it must be open and flowing.
2: blow fan is dead, (on high must work)
3: air flow through core is not flowing.

if the core is back flushed, like it should be ever 2years then its
not packed up, remove hoses back flush it. does it flow
yes, good, its not bad (if not leaking incab)
no, its packed up, so blast it some more with a water hose.
now its fixed. simple huh and not removing it.
now #3
all above is good but #3
air flow, so move all the damper by hand , got heat now?
if yes, you just discovered why. bad damper controls'
the FSM covers in details how , for damper. read it.
in usa its also at read it. read the damper sections .

My kenmore fefrigerator not cold anymore, what should I check first pls!

Hi and welcome to FixYa. I am Kelly.

First check the freezer compartment for signs of ice build up. If the unit is running and not cooling. If you note ice build up do the following.

1. Unplug the unit.
2. Remove the contents of the freezer compartment.
3. Place a fan blowing into the freezer compartment of about 2 hours. (Makes a water mess. Mop and rags required)
4. After 4 hours wipe the internal cabinet dry.
5. Plug in the unit and let run about 30 minutes.
6. Reload freeezer contents.

This is a manual defrosting procedure. It will only provide relief from the symptoms of no cooling for around 2 days. If the manual defrosting returns the unit back to normal temps then you will need to have the unit serviced and the automatic defrost circuit repaired.
The problem can be
1. Defrost control,
2. Defrost heater element,
3. Wiring, or
4. The defrost thermostat.
Any one of the 4 can cause the problem.

If the compressor is NOT running at all the problem can be
1. Defrost thermostat.
2. Defrost control
3. PTC start relay or the KliXon thermal overload (2 part Assy)
4. Run capaicitor
5. Compressor
6. Temp control.

You did not provide a model number in your post so all of the above are GENERIC terms. If you need specific information you will need to respond with your model number.

Thanks for choosing FixYa.

The air conditioning blows out of the defrost vents. It only works on high now but use to on low. It use to come out of the front vents ocassionally. We did replace the heater / air control unit in the...

Seems like the dampers are partically closed,look under steering column and see your duck work for the vent system.Follow it back to the blower box.Unhook if there, turn on ac, if you get full air, nice and cold on low and high you have blockage in your vent duct work,check the vent line that diverts air to the diffrent selected vents. Also check for vent disconnection around sterring column,and defrost vent area.

Heating / air conditioning control stuck to front defrost vents

There is a vacuum leak under the hood. Find the vacuum line on the passenger side where it comes through the firewall and follow it to the engine. You system needs vacuum to operate and without it the default setting is on defrost for safety reasons.

Climate controls

Car manufacturers use the defrost mode as a default for safety reasons. Being they want you to be able to defrost the windshield no matter what. So when something goes wrong the system automatically goes to the defrost mode. You most likely don't have the vacuum hose connected under the dash at the climate control assy. Or if this vehicle doesn't use the vacuum hose style you may have not plugged in one of the connectors under the dash or behind the climate control assy. Good luck.

Fridge keeps on freezing everything inside of it

This refrigerator only has one thermostat located in the fresh food compartment it is designed to activate the sealed system (cooling) until it reaches approximately 37 deg f in the fresh food compartment. The damper controls how fast the cold air can move from the freezer compartment to the fresh food compartment. Allowing you to control the temp in the freezer by controlling the flow of cold air to the thermostat.

You have one of two problems.
#1 your thermostat is no longer opening when it achieves set temp. fix = replace thermostat pn 61005798 $35
#2 your damper arm or assemblie has broken. Fix = Replace damper or broken arm and actuator.
damper assembly pn12001377 $44
damper actuator pn 61002000 $2
damper arm pn 61001999 $2
