Changed the heather core over the weekend on a 2001 S-10 4WD, 4.3L V6. Now the remote locks don't work - any ideas?

Thanks!

 

Did you forget to reconnect the RKE module located just behind the DLC under the driver side dash to the left of the steering column?

 

Is that a wire? Left of the column there's the fusebox, the wire that goes to the door-light switch. There's an interface that looks like it for connecting to for diagnostics, it's still dangling (waiting til this is fixed before putting all the panels back on) but it doesn't connect to anything.

 

The remote key less entry module (RKE) is located and attached on the flip side of the instrument panel sound insulator. This is the same panel as the dlc (obd connector) and is just behind it. If you removed this panel and disconnected the RKE then the remote locks won't work.

Thanks for your help with this - I'm afraid I'm having a hard time telling what's the RKE, dlc and obd. I have a wire dangling in the region just left of the steering column, but I just can't seem to find a mate for it.

 

The RKE (remote keyless entry) module is a rectangular box that is mounted to the trim panel just above the brake & throttle pedals on the driver side. The DLC (data link connector) is the connector visible with the trim panel installed and is what you connect to in order to scan for stored trouble codes (CLICK HERE for a page that explains the DLC). After removing the screws that hold the trim panel in place and locating the DLC, drop the trim panel down. The RKE module will be located between the DLC & the firewall slightly off to the side.

It is also possible that you did not properly reconnect the grounds.

Here's an image that might help - note the arrow pointing towards the front of the vehicle:

 

Okay, got it. Feel a little silly I just hadn't replaced that trim panel yet, didn't really think of it as a component.

I still have no AC though and a couple wires dangling. Are there sometimes wires that aren't used, like for options this car didn't get?

 

Some are, some aren't. Labeling makes reassembly much easier. I have had that bite me on a few occasions.
