Sorry heater core no hoses inside car

If you don't mind the cold remove hearter hoses and connect together with pipe and clamps.

Removal - FRONT HEATER CORE

WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury or death.

WARNING: Refer to the applicable warnings and cautions for this system before performing the following operation. Failure to follow the warnings and cautions could result in possible personal injury or death.

1. Remove the silencer boot fasteners located around the base of the lower steering shaft from the dash panel so that it may be pushed aside.
2. Remove the brake lamp switch from its mounting bracket.
3. Disconnect the power brake booster input rod (push rod) from the pin on the brake pedal arm.
4. If equipped with power adjustable pedals, remove the adjustable pedal assembly.

NOTE: Take the proper precautions to protect the carpeting below the heater core from spilled engine coolant and have absorbent toweling readily available to clean up any spills.

5. Remove the heater core tubes.
6. Remove the two screws that secure the heater core mounting plate to the HVAC air distribution housing.
7. If NOT equipped with power adjustable pedals, pull the accelerator pedal upward (Accelerator Pedal) and push the brake pedal downward (Brake Pedal) for clearance to remove the heater core from the air distribution housing.
8. Remove the heater core by carefully pulling it straight out of the side of the air distribution housing.

Installation - FRONT HEATER CORE

1. If NOT equipped with power adjustable pedals, pull the accelerator pedal upward and push the brake pedal downward for clearance to install the heater core into the HVAC air distribution housing.
2. Install the heater core by carefully pushing it straight into the side of the air distribution housing.
3. Install the two screws that secure the heater core to the air distribution housing. Tighten the screws to 2 Nm (17 in. Lbs.).
4. Install the heater core tubes.
5. If equipped with power adjustable pedals, install the adjustable pedal assembly
6. Connect the power brake booster input rod (push rod) to the pin on the brake pedal arm.
7. Install the brake lamp switch into its mounting bracket.
8. Install the silencer boot around the base of the lower steering shaft on the dash panel.
9. Reconnect the negative battery cable.
10. If the heater core is being replaced, flush the cooling system.
11. Refill the engine cooling system.
There you go.

Hi:
The cost of the heater core should be $100.00 or less. However, the labor is going to hurt because the dashboard has to be removed. I believe the flat rate is around 6 hours x labor rate.

If you have any other questions, let me know.

If its the heater hoses and line to the rear heater system
You can use regular heater hoses and no need to spend that much money for an original parts
but if its the heater core that need to be replaced than its all labor to get to it

Sound's like your heater core is leaking and needs to be replaced. So your blower fan is inop in any speed?Something could have been damaged from the coolant. Do you have a multimeter to do some testing?

So the light's are flashing like in a sequence or they stay on for a while then go off then come back on later?Have you checked all the fuse's?It says you have to remove the glove box to replace the blower motor but I bet if you look you can find the wire going to it without removing the glove box to do some testing. Put the key in the run position turn the blower motor on high you should have battery voltage on the dark blue wire and 2 ohms or less on the black wire with a tan stripe let me know what you find.

Yes that is most likely the problem

Are you talking at the front bumper or firewall?
