Take a look at the drivers side wiper nut, I actually just did this today
Pics in order of appearance:
!. Pop the caps off the wipers, 15MM socket for the nuts and pull the wiper arms off. Mine were on there pretty good, used my 30 year old Snap-On battery terminal puller to pop them loose.
2. Remove the 4 plastic press-in clips along the front of the cowl cover.
3. Pop the washer hose holder out also, lift front of cowl cover up, mine wedged up nicely on the hood struts, didn't need to remove it.
4. Voila, the culprit is all the way to right, bolt and rubber grommet circled in red.
5. I have the bolt half-way out, 10MM socket, it fits down into a metal sleeve which is part of the rubber grommet, metal bolt was squeaking inside metal sleeve, a little grease on the bolt, a little WD-40 on the the rest of the linkage, reverse steps, listen to the radio in peace again
Hope this helps
