The drier is for the A/C , the Evaporator is inside the dash of the car, the drier/accumulator is directly connected to the evaporator, and that has nothing ot do with the heater.....so I dont know what hose you want.

MY 1996 CHEV,TRUCK BLAZER 4WD 4.3L SFI 6 CYL A/C WILL NOT COME OUT OF AIR VENTS OUTLETS IT COME OUT OF DEFROST VENT IS IT THE HEATER BOX? PLEASE HELP,THANK YOU


25810307-fxpq3y20ry0r1dabvswcgqqy-1-0.jpgI've had the same problem, this hose (click the box) is a lot of times disconnected for what ever reason. Hooking it back into the nipple solved this same exact problem you're having. Well the click box thing didn't work. Look at the black vacuum "T" just to the right of the brake booster, the hose that goes over to the fender unhooked is the hose I'm talking about. Nipple is sticking outwards underneath where that hose is under the rusted metal flap.

The radiator cap is on the box on the box on the firewall not on the radiator but never heated up before he added the other hose n it looks backwards top hose on box to bottom of radiator n vise versa I...


the top box as your calling it is the coolant expansion vessel and the cap is obviously for topping up coolant, the hose on the top of this vessel is the hose that carries the expanded coolant from the engine so that there is not to high a build up of pressure,the hose at the bottom of expansion vessel goes to the bottom hose via another set of hoses which link up the heater matrix, there is a top and bottom hose on the radiator , the top goes to the engine with the thermostat inline ,the bottom hose goes to the water pump for circulation .let me know your vehicle make and model , year etc and i'll find a diagram for you

Need to find location of the A/C thermostat sensor. It has failed and I need to replace it.


This sensor is located on heater box but goes inside to the ac evaporator, it sticks into the fins of the evap core, some times the heater box must come out and opened to replace, the dash will need to be removed and the ac system drained but some times the sensor can be pulled out throught he hole it sits in and is rubber mount to box and there may be room so that with some needle nose pliers you can grap it and pull it out, heres a picture of it. i hope this is the sensor you are looking for, there are other sensors in engine compartment on the dryer and the hose asm.good day, hope this helpsjohnjohn2_93.gif

Im looking for the name of what the blower motor sits in i cracked it and the antefreeze is comming out


The blower motor is encase in what they call the evaporator case, which is what holds that evaporator and heater core.The heater core is your heat source and your evaporator is your cooling source(for cool air) You said you were leaking antifreeze so you will be needing the heater core assembly...Any more questions get back to me...I'M HERE TO HELP!!!

I need to install an evaporator core in 1997 xj6. Any tips or suggestions?


Ok , I will try to guide you as simple as I can :
1- Remove the Heater / Cooler unit this is how : * Disconnect Battery ground cable
* Recover AC gas or empty it in open space
* Drain radiator coolant only
* Remove instrument panel for access
* From under the hood disconnect AC pipes at the evaporator , by removing bolts , discarding O-Rings and make sure to install blanking plugs so that no dirt goes in.
* Disconnect heater hoses from heater matrix pipes , by releasing the spring band clips and make sure to blank the pipes
* From inside the car , remove driver footwell duct , by removing the screw and then removing the duct
* Remove upper steering column lower fixing , nuts and bolts
* Remove upper steering column upper fixings (Bolts) , and allow column to rest down o the floor
* Cut cable tie which secures console harness to LH blower duct
* Remove LH fan motor duct (screws)
* Remove passenger side footwell vent (nut)
* Cut cable tie securing console harness to RH blower duct.
* Remove RH fan motor duct (screws)
* Disconnect Heater/Cooler Connector
* Disconnect drain tubes from Heater/cooler assembly
* Disconnect A/CCM connectors
* Remove evaporator pipe support bracket fixing.
* Remove Heater/Cooler assembly fixing , by removing lower nut and upper nut
* Remove tape securing RH rear footwell intermediate duct joint. Remove duct to clear access
* Remove tape securing LH rear footwell duct
* Remove Heater/Cooler assembly from car.

2- Remove AC control module 3- Remove evaporator pipe seal plate 4- Disconnect heater tempreture sensor 5- Remove footwell servo motor from heater/cooler unit * Disconnect connector
* Remove screws
* Remove motor complete with bracket
6- Disconnect evaporator sensor connector * Detach heater/cooler connector
* Detach evaporator sensor connector
* disconnect connector
7- By now you can see one upper and one lower case * Remove heater/coolent unit upper case from lower case
* Remove screw
* Remove 15 clips
* Remove upper case from lower
8- Remove evaporator from case * Remove sensor and clip

You are done , make sure to replace all seals that you see to make sure that every thing is ok and you do not have any leaks after installation.
Installation : Reverse order and after installing make sure to do a pressure test to make sure that there are no leaks
