When it rains my passenger side wiper blade hits the stop or bottoms out and makes a clunking noise. I need to know if it is an adjustment or a linkage replacement

bent/broken wiper arms under the base of the windshield..remove the vent cover and service/replace broken parts.

has been moved or the one fitted is bigger that the one it was originally set to. take the cap off the wiper arm and undo the nut. then wiggle the wiper blade arm until it comes off. then put back on and leave an inch gap from bottom off the window to the wiper. tighten the nut up and check that it works ok without going over any of the rubbers on the winds screen. if it does re do it and lift it a bit more up. then it should be fine after driving over 30mph then.

when the wipers are off make sure the driver and passenger wipers are at same level on windshield
you can adjust them so they don't go off the edge or hit the bottom.
if they are hitting off the edge and hitting the bottom as well you need to check the linkage since it may be worn out.

I had the same problem with my 99 Silhouette...after they put in a new windshield wiper kept going over the side of the window and tearing the blades up....ended up that the wiper arm was out of adjustment ....they came back and readjusted and it was perfect

The bar that connects to the arm that connects to the motor came off. Remove wiper motor to get to that connection, Autozone will have that part in there (help) line.

Hello angela_brosc. My name is Roger and I will help. The Rain-Ex weather beater wiper numbers are. Driver side RX30226 and the passenger side number is RX30218. There is not a listing for a rear wiper blade. Should you need further help please just ask. Please rate the answer you received. This wat I know it was helpful. Thank You for using Fix Ya. Roger

Sounds like you just nee to remove them and reinstall them in the correct position. Take them off, run the wipers for one cycle until they park. Install the arms so the blade is about an inch above the bottom of the windshield.

the main motor is on the passenger side. there is a link between the to that operates the driver side wiper. the link has to be replaced.. what i am finding is that you have to buy the whole wiper kit which is approx.70 dollars instead of just buying the link or gromet.

The 23 should work on the drivers side but you will need a 19" on the passenger side.
Hope this helps and let me know.
Regards,

Yes the spring in the arm is weak, replace the arm and your problem will be solved.
