Your best bet for replacing the rear window on your 1993 GMC 1500 pickup would to talk with your local mobile windshield replacement people, the rear window may be glued in the same way the windshield is glued in. The code 43 is related to the knock sensor circuit. Check the connection at the knock sensor which is located near the starter. If the connection is damaged or loose it will need to be repaired. If the connection is OK then chances are you have a faulty knock sensor. If you find you need to replace the knock sensor please note that when you remove the old knock sensor coolant will flow out of the hole. If you have the new sensor ready to install and you are quick you should not loose much coolant.
