Help me locate these ground points

K, My wiper issue is down to the ground points. I was told what ground points I have to check but not 100% sure where exactly they are located;

1 - Wiper relay ground point G101 located on engine block.

I'm thinking this is the two wire ground point on the corner of the engine block, very close to the bracket that holds the top of the trans dip stick. Two wires, one looking like the other end of the Negative battery wire.

2 - Wiper motor ground G300 located on left cowl ground block.

Where the heck is the left cowl ground block?

3- Wash switch ground G200 located on instrument panel ground block.

This must be under the dash, next to the steering column. I'll most likely have to remove the bottom cover to get to these ground points.

I live in New Hampshire and DON"T have a heated garage (yet). Not fun working on your car when it's 30 deg out! These wipers are driving me nuts! 98% of the time I can press the washer button and the wipers will squirt & wipe a short duration. I then click the wiper dial to the 1st indent & the wipers will run in the slow speed but that's it! any of the other settings & I get nothing. One time the wipers stopped in mid position and would not move. Two day's later while driving down the road I hit a bump and the wipers parked and now working as explained above BUT they could stop at any time! NOT fun when it's snowing here!

Thanks All. Once I get the correct locations I might take some PICS for the others here.
