Hello. My name is ***** ***** I will be helping you today.

This is usually a bad clock spring. Do you have any tools to do some testing?

Is the check engine light on?

Customer: replied 7 months ago.
No
Expert:  Wayne Crawford replied 7 months ago.

Lets start by checking the G100 ground. Its located on the left inner fender under the cruise control servo. Check it to make sure its clean and tight and got good continuity to the battery ground. Let me know if that all checks out.

it looks pretty rusty and when i checked for continuity if i did it right i took one lead to the G100 ground and the other to the negative side of battery i got a reading of 0.39 ohms
Expert:  Wayne Crawford replied 7 months ago.

If it looks pretty rusty start by getting rid of the rust, taking it apart, cleaning, greasing and reconnecting it all.

When you check continuity you want to check from the wire close to the ground point to the battery. Poke a hole in the insulation.

ok cleaned it up still getting same reading
Expert:  Wayne Crawford replied 7 months ago.

OK sorry for the delay. So you are piercing the insulation on the wire and getting this reading there, correct?

Take out the horn relay and try the turn signals. Do they work normal then?
