Will a 1996 chevy blazer LS 4wd differential fit into a 2000 chevy blazer LS rwd rear end ?

Measure the lenth of both rear ends. see iss all hardware will bolt up without fabrication. if its the same size it will work. But im afraid being a 4 wheel drive it will be geared lower then a regular pick up/ Drive shaft may work but if not it would have to be shortened or lenghthebed. alot of work. Brakes you could leave the non drum breaks on better stopping power. I honestly believe you would be better off just going to a scrap yard and find one very easy to remove and replave few hour job.

Rear wiper comes on all the time

Remove the rear wiper relay. The relay works just like a fuel pump relay or any other relay.
Here is example of your relay system and how to test it: Remove the relay and turn the ignition switch on and the rear wiper should not operate. If the motor works with the relay out then seek out a priest as the motor is haunted. To test the circuit do the following:
Bypass the relay with a piece of wire, (preferably fused). This means: Remove the relay and put the piece of wire in place of terminal 30 and 87 in the cavity where the relay lives. Even if you don't use a fuse all you are doing is giving the wiper motor the same voltage it would be getting if the relay was closed. All electrical diagnoses should come from the relay. It gives you the input and output for the accessory. The input is 12v hot on terminal 30. This usually this is constant hot wire from the main buss line on the fuse box. The 87 terminal goes to the fan itself so that the output of this terminal will be a grounded motor waiting for voltage. The 86 wire on this relay is normally fed through the fuse box via the appropriate fuse and gets voltage when the ignition is turned on. The 85 terminal on the relay is the field ground and energizes the relay. This wire comes from the switch. When the rear wiper switch is turned on it sends ground the relay terminal 85 which closes the points of the relay and allow power to travel from the 30 terminal to the 87 terminal. This gives power from the 30 terminal to the appliance at the other end of the 87 terminal. The grounded rear window motor receives this power, begins to spin and operate the wiper. By the way relays have a failure rate of about .015% so the problem probably isn't the relay itself.Joe

    Rear window will not open or release , can hear electric release

    you will need to check all the fuses first, then remove the pop window switch and check for power at switch, and power going through switch when button is pushed, this button is on the dash, if there power then you may have a bad release motor,if your blazer does'nt have a hatch release on the dash then you will have to remove the panel on rear door and test there .

    I have an electric rear window in my tailgate that won't go back.

    Yes you can unbolt it from the regulator that it rides on. You should see a couple of bolts holding it in place unbolt it and pull it out so you can work on everything and then put back in.

    My rear window is stuck down in my 1989 k5 blazer.

    If you can hear the motor turning but window is not moving, then the window most likely came off it's track. You will have to remove screws and pry off the door panel and replace window on track

    My rear window wont go up or down 1990 toyota 4runner

    I am assuming you have power windows, more than likely your power window motor regulator needs to be replaced. But first your window could have came off its track, to check to see if this is the case (the easy way):
    1. inspect the window make sure it doesn't appear to be visibly crooked or cockeyed
    2. hit both the front and back of window with the palm of your hand forcefully, but not hard enough to hurt yourself of course :)
    3. check to see if window will go up and down now
    4. if this doesn't fix it then it's time to replace the power window motor regulator, unfortunately this isn't a job for the average joe (especially if he doesn't have the appropriate tools) so you'd need to take it to a shop
