'95 850: Fixed the AT and broke the cruise control

I have been posting about how my AT would generate an error when I
shifted down into "3" while descending a hill and it would cause the
dreaded flashing yellow arrow and the check engine light. On the eighth
trip to the shop, with the sleuth of Mike, they replaced the pnp switch
on the AT and now that problem is fixed.

However, now the cruise control doesn't work. I checked the cruise
control fuse and it is OK. Is there some obvious relation between the
AT and the cruise control or a reason why working on the AT could kill
the cruise control?

I told the dealer about it, but haven't scheduled to take it in yet.

 

Look under the battery there is a vacuum pump check to see if any vacuum
lines are off

"*-344-*Never Forgotten"
Is for the New York City Firemen who lost their lives on September 11,2001.
The official count is 343, but there was also a volunteer who lost his life
aiding in the initial rescue efforts. And I will never forget them as
long as I live,
nor should any American.

 

While the PNP switch allows the starter to engage when the the switch is
closed, it will at the same time turn off the cruise control module. The
cruise control will turn on again when the PNP switch is opened.
So - yes there is some obvious relation to the work done. Maybe the PNP is
permanently closed, even letting you start while in Drive position.

I checked the starting while in drive and that doesn't work so I can't
verify this problem. I will be scheduling to take it in this week.

 

I looked around the battery but couldn't see much so I can't verify this
problem. I will be scheduling to take it in this week.

 

When I called the dealer to make an appointment to bring it in and
suggested that they may have forgotten to connect a hose or wire, they
told the mechanic and he said "oops, I forgot to reconnect a hose.
Bring it in and it will only take a couple minutes to fix it."

Thanks much.
