1.Check the wire that goes in the back window.
2. Should be a little clip like the one that attaches on the grid.
3. Its most likely up in the top corner.
First make sure your fuse to the rear defroster is good.Then test the wires that plug into the defrost bars on the rear glass, there are two plugs one one each side of the rear window.Take a tester and unplug the wires and test them for power, if no power you must have a bad connection from the fuse box to the back glass.If you have power and defroster still wont work you have bad defroster bars in the back glass, hope this helps you.
With a volt meter or a test light ,it also might be a fuse
screen wash pump working fine but rear wiper wont work.
If all of those arent working then the first thing I would do is check where that stuff is grounded. In mine it is located on the wheel well wall on the rear driver's side. Make sure the ground isn't corroded or unhooked. Next thing would be to ohm test the fuses for these and see if the fuse is bad. Good Luck.
Check ALL of the fuses with a test light then you will know they are good
Not while it is in the fuse holder. Pull it out and if you cannot look and tell if it is blown or not, test it with an Ohm meter.
you probley have a vacume leak due to a broke or craked hose u should take it to a shop for a pressure test if u do not have a vacume tester.
A/C on/Defrost on during KOEO (Key On Engine Off) test.
you test it out
It is located on the passenger side front fenderwell tub, among the two relay's, one being the A/C relay, the other your fuel pump's relay, both are bolted to the rear of the fenderwell, close to the firewall, the fuse for the pump is a capped single fuse plastic receptacle, there is a also an open red wire, that is the test port for your fuel pump, apply 12v to this red wire to test the fuel pump itself. jr
To test it effectively you have to disconnect one end to cut out feedback.
Use a test light, Hook up a test light to the ground post of the battery and check both sides of the fuse. If the light lights up on one side but not the other side the fuse is more than likely blown. If the test light lights up on both sides the fuse is good.
