hello and thank you in advance

hello group
I bought a 95 sc not knowing much about it and now i'm going to learn alot about it with your help it has all the classic problems and i'm going to the interior section to list them - - i'm afraid a dealer is going to have to tackle these gremlins i am hoping i can do them myself though - - with your help

What kinds of problems are there? You should get a signature listing your year, miles, and other general info like that for future reference because each year Riviera is quite different from the next.

what"classic" problems are you talking about?the seat warmer comes on by itself and warms your bum in the dead of summer and cant be shut off? or the supercharger coughs on acceleration instead of whining? or the hood pulls a Christine on you and shuts itself on your head while your working under the hood? those problems? dont worry they are quite normal and nothing to be concerned about.

llan, i will update my profile of my 95 sc with 123xxx miles - sorry about any bold mis punctuations[/img]

Hello, Jeff. Thanks for the image. Could you give some more info about what this part is, and the problem you are experiencing? Thx.

This is one of the HVAC controllers.

Can someone explain where the position of the Blue plastic gear should be in relation to the other gears, Normally. ???
I forget, but I think this one needs to be indexed properly.
It appears to be out of Sync.

Try removing the white plastic gears and repositioning the Blue gear so that it is in the center of it's normal travel (rotation) and re-installing it and trying to operate the HVAC system and, if this actuator is rotating then continue until you find the center of it's operating range.
Or as Randall did and make a 5volt powerpack to operate the Actuator and try to reposition it that way. If the gears operate with 5 or so volts you have a good Actuator and just need to center or index it properly.
Then everything should be working properly.
Good Luck and report back what you find.

Is that the lil bastard causing my problems....wow

Interesting, just tonight I had my pass. Side actuator out and was looking for the writeup about it with no success. If somebody could locate that writeup and please add it to the 'write-ups' links I would also appreciate it.

Jeff, in your user profile add the car's info to the 'signature' area and turn on your signature.

Derek, is this the write-up you are talking about?

https://rivperformance.editboard.com/interior-f20/write-up-hvac-assembly-t2500.htm

If so, it's listed in the Interior Write-Ups index.

a 9 volt battery worked for my motor - moved the grey female hub to the 1oclock position on the outside case, i still have to check if that solved anything

No, there was one where somebody showed how to repair and/or reindex the gears inside the actuator.
