And, if that doesn't help .... Posted by RS [Email] (#15) [Profile/Gallery] (more from RS) on Thu, 6 Mar 2014 06:12:01 In Reply to: Keyswitch, stiffness in lock cylinder and key linkage, RayF, Wed, 5 Mar 2014 07:58:57 Members do not see ads below this line. - Help Keep This Site Online - Signup |
it's probably the main relay - no accessories and those two dash lights is a classic indication that it's got an issue.
The relay is in position E in the fusebox.
After a decade or so, the contacts become pitted because a *lot* of current goes through that relay. A major jarring like you describe can knock them out of alignment and the contacts can't make a good connection.
On my car, sometimes the accessories wouldn't work when I started it - slamming the door or hitting a bump would restore their operation.
Finally got tired of that, studied the schematic and decided that the relay was the issue. Took the cover off the relay, saw that the contacts were badly pitted. Cleaned them up with a Dremel using a small steel brush. Put it back together, inserted it back in the fusebox, and haven't had any more issues with it.
Since then, I've looked at main relays from other 900s. They all have the same degree of pitting of the contacts.
