Bobby,
Sorry you got the task of replacing a heater core. But never the less there is a fuel cut out /roll over switch located in the passenger kick panel and the harness runs up thru the dash. Two things could have happened.
1-the fuel cut out triped. Reset by pulling the passenger side kick panel and reset by pushing the red or yellow reset button. This should cure the problem.
2-the harness to the cutout switch was disconnected while working under the dash or pinched while the installing the blower assy. you can take a DVOM and check the resistance at the switch harness while disconnected from the switch. If the meter reads less than .003 you have a short. If not while disconnected check the switch by depressing the button and check across the terminals. The meter should have an audiable mode and listen for a beep. This means the switch is good. If no noise replace the switch.
Good Luck.

Disable passenger airbag


There is no user operated key to disable passenger airbag like on most newer cars, for what you are attempting just disconnect the battery! This should allow you to remove the dash without activating the airbag!

Was there a problem BEFORE the maintenance or only after?

Car is running in 'limp mode' so it won't drive correctly.

Did you have to pull the dash to get to heater core? IF so, something's still loose back there.

How to Replace the Heater Corein a Chevy Impala

Replacing your Chevy Impala'sheater core is no easy task. There are several parts you must carefully removeor reposition to disconnect the core from the heating, ventilating and airconditioning (HVAC) module. This module and the core are located behind thecar's floor ducts.

1. Jack up the car and drain the Impala's cooling system.Loosen the water pump's drain bolt and let the coolant drain into a pan. Closethe drain bolt and lower the car afterward. 2. Remove the heater outlet and inlet hose from theheater core (reposition the hose clamps to do so). Take off the right consoleextension panel, body control module and left side extension panel on the frontfloor console 3. Disconnect the leftinstrument center support bracket (pull away the carpet at its bottom to reachthe nuts). Remove the accelerator control pedal from its position in the frontof the dash. 4. Disengage the center floorducts by raising the outlet duct while pushing the ducts down. Rotate theoutlet duct forward in the car and pull down to remove it from the HVAC module. 5. Use a small chisel to removeall the heat stakes from the heater core cover. Loosen the nut behind the fuelline bracket. Remove the dash panel's stud at the heater hoses. 6. Pull the core's cover downenough to reach the HVAC module's locating pins. Slide the cover rearward untilthe drain tube clears the dash front. Remove the cover by sliding it down,rearward, and to the right. You can now remove the core.
Installing the New Core
1. Install the new core into the HVAC module,attaching a new seal onto the drain tube. Attach the core cover from the rightside, sliding it up and forward into position. 2. Align the draintube with the front dash hole and the core cover holes with the HVAC locatingpins. Install the core cover screws, cutting and folding back the soundinsulator near the center screw to ease that screw's installation. 3. Reinstall the dash panel stud at theheater hoses, tightening the nut behind the fuel line bracket. Align the centerfloor duct with the HVAC and push it up while rotating rearward to install it.Put the floor ducts and outlet duct back into the Chevy Impala. 4. Attach theaccelerator control pedal. Pull the carpet back and position the left centersupport bracket, then tighten the bracket nuts. 5.

Need to change heater core


The dash has to be removed to gain access to the heater box, a factory repair manual is a 100% must have for this job. The heater box then comes out and is split open to replace the core.
this is not a job for anyone except a experienced mechanic, about 10 hour job, a factory service manual is a must, u can buy a factory manual here.

Heater core


You have to pull the dash almost out to replace the heater core. first drain the coolant and remove the heater hoses in the engine compartment. Next lower the steering column. there are 4-5 8mm screws onthe top of the dash,and tw 13mmbolts on the sides remove the kick panels to see them. Also remove the airbag module on the tranny hump under the dash.when all is unfastened you can pull the dash back on the passengers side back and almost put it on the seat. you will see the heater core on the top of the heater box. Discharge the ac and remove the heater box fasteners in the engine compartment . pull the box down inthe cab of the truck r&r core. sound worse thatn it really is good luck

Disconnect the battery.
Disconnect Air Bag on passenger side and remove.
Remove air duct bezels for defrost.
Remove all screws.
Remove Glove compartment entirely
Remove metal shiled behind glovecompartment
Remove screws from undeneath dash board
Remove Speedometer and very carfully loosen the string that moves the indicator so you don't break it. RD2L indicator string.
Remove Radio, lighter, ash tray,
Remove two screws by side of dashboard near the door hinges, \
Remove all support brackets underneath
Remove all electrical connections notice where they go if not sure color code them with tape.
Remove all screws from heater cover
Remove all screws from air ducts that might need to be remove.
Dashboard should lift up once all screws are remove and you can pull towards you.
Lower the position of the tilt wheel if available.
Remove blower motor for heater if necessary,
Be careful with the connector for the heater door. You can remove the heater door carefully, don't mess up the felt
disconnect heater hoses remove heater core.
When connecting heater hoses, make sure you connect them the same way again, and apply sealant to the hoses before tightenting clamps. You sure like hell don't want a leak after you mount everything back.

I ran the heater while I had the dash board off just to make sure there were no leaks. Reverse procedures to install at your discrection. Suggest you follow all steps in reverse so you don't end up with screws you can't figure out where they go.

Its about a two day job if you do it alone. They charge 900 at the dealer for doing this. Can't understand why in the world FORD just doesnt make an access system so you can remove the core without removing the dash board. Yes I do...........MONEY! No wonder American car mfg. are in such a pitiful state the the foreign car market is kicking ***. American cars to change the fuel pump you have to drop the tank. Japanese cars to change the fuel pump you go to the hatch over the tank remove the hatch and remove the pump. Get the picture!!!!!! Good Luck.
