I snagged a "new" climate control unit from a 2000 C70 today, and of course now I'm not seeing any flashing lights at startup with the old one still installed.

this evening when I started the car and turned on the radio, it asked for the code, which I had already called the dealership for.

Entered the code, and the radio appears to function.

However, I have no antenna mast, and didn't have anything to test the cd player or tape deck with...

I'm still ...

Gotcha, looks like another trip to the pick and pull will need to happen soon.

I've seen some sources that say my '98 GLT w/Dolby should already have a 4x50 amp installed under the passenger seat, so the radio would just be a straight swap.

Is it necessary to get the amp from a C70 to make the 901 work?

I'm not really trying to do a full swap of all the speakers and whatnot.

Just found an SC901 in a wrecked C70 at the junkyard, so figured I'd grab it for $20 as well as the climate controls.

The car does have it's original axles... just replaced a CV boot less than 100 miles ago.

nvm, answered my own question.

No CELs, No service light.

I don't know if this is just being nitpicky, or indicative of an actual issue.

Under mild/light acceleration, the car "rumbles". I don't know how else to describe the noise.
It is still accelerating, perhaps not as quickly as it should, but then again, it has 263k miles on it.

If I give it 75 ...

I was sitting in my car the other day with a few minutes to kill, so I pulled the radio and climate control cluster.

Pushed out the switches and blanks around the cabin climate sensor, and then removed the sensor itself.

I found it easier to pull it from the rear after pressing the tabs.

After ...
