First time user.need help. First of all my sc430 fob dont work,top wont work,tilt steering wont work,mirrors wont adjust,passenger window wont work or locks dont work.please help.

 

Can you tell us more about your car? What year is it? How many miles on it? Was it in a flood or accident? Did you check all your fuses?

 

flood 2002 124,000 miles checked all fuses.

 

Had it for 6 months.everything worked good until fob started not to work every now and then.and thats when the other stuff sterted not to work.did work intermittenly but now does'nt work at all.

 

Sounds like the car has some dirty contacts, most likely all in one place since they are starting to fail all at a similar time. How long ago was it flooded?

 

Don't know got it sold just got to get it fixed.

 

Getting tired of replacing modules and they don't help.any suggestions

 

How do you go about fixing contacts

 

It was flooded about late 2019 i had everything taken out and cleaned and new leather put in.you could see the water got on floor mats and that was it.

 

Thats funny about 5 things won't work in this circuit you would think it would be an easy fix.

 

Can you send me in the right direction.where to start.

 

This is not an easy fix. You probably have contacts and harnesses problems. Water has gotten in and corroded the harnesses contacts. Unless you can locate all connectors, test and replace the bad one, I don’t have other suggestions.

 

At least thats a start thanks

 

That's pretty much how. If you have the SC430 wiring diagram, I'd look for a point where they are all close together or all in a connector and start there. If there is corrosion, you'll need to replace the connectors. If the contacts are just dirty, you can use contact cleaner with cotton swabs/pipe cleaners/toothbrushes to clean them with. But the quickest, most reliable and longest term fix is to replace the connectors or wiring harness.

 

Most likely a bad ground. Electical manuals are cheap on ebay.
