    I finally Replaced the unit and traced all the wires. Several fuses were removed to keep things from shorting . Found where an aftermarket alarm system was slopily installed causing short circuits in the car.

    Everything is now working including the rear defroster.



    Thanks for the help.

Rear defrost don't work


There is a fuse in the panel by your left knee. If that is not blown then the problem is the ETACS module below the fuse array. You should hear it click when you activate the defroster but the engine must be running for this feature to be active. If the fuse is ok and the relay clicks ok then it is a wiring problem or open heat element in the window. Use a DVM to trace if power is on at window first. Have no idea how the heater element can be fixed and dealer may have a fix for that short of replacing the entire window.

Tryin to locate the keyless entry reciever and the Set/Off button


The ETACS unit, which controls the alarm, is bolted to the dash chassis and is located immediately behind the climate control cluster. You need to gain access to this unit to code a new remote. Technically, you are not coding the remote; what you are doing is re-programming the ETACS module to remember and accept the secret code transmitted by the remote. The ETACS unit is designed to remember and accept up to two remote codes. If you wish to add a third remote, the dealer must program the third remote to utilize the same code from one of the other two remotes (called code-saving). There is no way to do this yourself.

The Project

1) Remove the dash facia using the "Easy Dashboard Removal" DYI posted
here by member kmr327.

2) Remove the four screws securing the climate control cluster, pull it forward, and remove the wiring harness.

3) Using a flashlight, (and cramming your head), find the sticker that marks the location of the set switch on the ETACS unit. It is on the right side of the ETACS unit, below the antenna input (the antenna can be unplugged -- it utilizes the same type connecter as the AM/FM antenna). Note the positions on the sticker for "Off" and "Set". By default, the switch is in the "Off" position, which is the normal functioning position. Next to the sticker is a small piece of tape covering the recessed slider switch, which you can not actually see. Remove the tape with a razor blade or by picking at it with your fingernail.

4) Once the tape is removed, use a jeweler's screwdriver or other similar small tool to flip the switch into the "Set" position. (Note: if you unplugged the antenna from the ETACS unit, the antenna must be plugged into the ETACS unit at this point and the car's battery must be connected). You are now ready to code the remote. NOTE: When you code the new remote, you must re-code your old one at the same time or the old one will no longer work. To code the remote, press either the lock OR the unlock button of the remote once. Do the same thing for the second remote. Try to do the second remote within two seconds of the first one. Slide the switch back to the "Off" position. Verify that both remotes function. If they do not, set the switch to the "Set" position again and repeat the procedure. If you continually run into problems, try coding only one remote. I have heard on some of the forums that the second remote has to be pressed within a second of the first and that it may take several attempts to be successful. I did not encounter this problem.

5) Reassemble the dash facia.

Hope this information is useful!

How to program keyless remote


I just had to buy one too and these are the instructions I was given by the guy I bought it from. I haven't tried them yet. Hopefully they work for us both :).

1.Find the ETACS unit under the steering wheel first,there is a small switch onit.
2.Once the switch is located make sure your key is not in the ignition and set the switch from off to set.
3.Press keyfobs door lock button for one second, this sends the codes to the ETACS and stores it.
4.Do the same thing if you have 2 remotes for the vehile.
5.Now set the ETACS switch from set to off.
6.Remotes should now be programed.
