Hello All
So, it's always the case that problems come in pairs which makes diagnosis difficult. In the morning, I had 2 topics with the wave runner and in the afternoon 2 topics with the 91 GT.
My battery kept going down. Well, the hatch is not closing properly after I had to replace the latch with an after market latch because the original one cracked. With time for some reason the rubber bumper in the latch (not the stop below) has worn on the edge and this caused intermittant opening. That was on my radar screen, but I started to get eratic interior lighting as well.
Surprise, surprise, both switches were corroded. At first, I heard the relay (?) only clunking on the drivers door switch when actuated in situ. This seemed odd, because no relay clunk on the passenger door and no relay clunk on either doors of the 90 GT, which has the interior lights work correctly. After a while the relay stopped clunking when I depressed the switch drivers side. Then, the passenger side started clunking... This led to dismounting the switches and looking in closed and open positions.
These cars generally have a high build quality but the switch contacts are really not so clever here. Contact seems only across a very small circular rim of the silver mounting bolt to a copper wire crimp. Anyway, what is the procedure used to keep them in good shape? Guess I will tray some Deoxit and sand paper to improve the intermittent connections. Also, any idea why the 91GT makes a definitive relay clunk when the door switches are actuated and the 90GT does not? And, where is the damn relay? I could not find it in the schematics.
Cheers, John
PS: obviously somebody had been in there because the passengers side silver bolt is partially stripped in front... Wasn't me.
