just bought 93 blazer S10 4DR 2WD need to take wiper arm off not sure how to do it. Its hitting the hood grill on high have to adjust not sure how and is ther any way to stop the rattleing from the tailgate and back window

 

Not sure about the wipers, but I do know how to fix the squeaky back window. This may not be very technical, but take some tape (I used athletic tape) and make about 3 or 4 wraps around the U-latch on the window.

 

Wiper arm pry off with a large blade screwdriver and a block of wood to protect the paint. Below is how I fixed the back glass rattle. I have owned my S15 Jimmy since new. The back glass has always rattled. I adjusted the latch, used electrical tape. Adjusted the tail gate and any thing else I could think of. Well I had an idea in my head that if the catch in the tail gait was not so narrow that it could secure the glass much better. I measured the Dia. of the latch on the back glass and the opening in catch when the catch was in the closed position. The Dia. of the latch was 1/4". The Dia. of the catch opening is 5/16 ". However the end of the catch is narrower. I went to Home Depot and bought a 1/8ipsX 2" brass pipe nipple. The inside Dia. of the pipe nipple is exactly 1/4" and the outside Dia. was over 5/16". First I ran a 1/4" drill bit to ensure it was nice fit. Then I used my bench grinder to mill the outside Dia. untill the pipe nipple would fit inside the catch on the tail gate. Once that was done I used a dremel tool to cut the pipe nipple almost in half to allow the I/4" drill bit to enter and exit the remaining half without binding. I then cut the length of the cut away pipe nipple to match the width of the tail gate latch. I then used epoxy to secure the cut away pipe nipple in the catch of the tail gate. This eliminated 98% of the rattle. The last piece was to put a piece of tubing over the alignment pin (On the Glass). I have not had any rattles since this fix and it has been over 6 months. Black tape works for a little while but the rattle always comes back.

 

Attached are two pic's of my fix for the rear glass rattle. The striker pin on the glass has clear tubing over it and the catch in the tailgate has the brass fitting. I do have a little bit of grease on the catch assy. so the pics look like there is a lot of gunk but it just a little grease, and the bottom line is that I have eliminated the back glass rattle. I have had this car since new and the glass has rattled since day one. I have tried adjusting, tape and heat shrink tubing. Nothing lasted untill now. The car is quieter now than when it was new. My idea was to have a larger contact area on the catch to secure the striker on the glass. The brass fitting is epoxyed into the catch assy. It has been holding for over six months with out any problems.
