Thank you so much, I didn't realize how much I still rely on the forum on a daily basis.

No low coolant sensor on any 2000-2005 Bonneville...except the GXP with the 4.6 (sensor is in the overflow reservoir)

Some of the aftermarket radiators will have a hole for a sensor so make sure it comes with a plug for that hole.

Also, it should only be a single vacuum line going to the trans modulator.

Maybe you should post a picture of what you're working with and we can help you that way.

Sounds like just a weak/dying battery. Did you try jumping it or having the battery tested?

Pinstripe would have been a dealer installed option, no RPO code.

RPO label would be on the spare tire cover.

The front is no different than the rear, possibly even easier because there is more room to work.

Likely a bad airmix actuator for the right side temp.

You wouldn't be able to work on it in the car because the front bank chain goes behind the rear bank chain , meaning the rear chain would need to come off as well. The Northstar simply isn't designed to be worked on while in the car. You'd be better off just getting a used replacement motor.

What is your ambient temp? Your pressures are high. You have a problem. I'm guessing a clogged expansion valve (orifice tube).

Gonna be some of the lowest quality stuff out there, sorry.

I see the Northstar with ignition coil issues all the time. I know you replaced some coils and cleaned the plugs, but I would start with all new plugs and new coils. Even the cheap ones seem to work well: https://a.co/d/bFzTqnV

In my opinion, having heard dozens of different exhaust systems on the 3800...you won't find a growly muscle sound except for idle. Any higher RPM and it just sounds raspy.

Hopefully you get it figured out...but I'm guessing its a blower motor problem.

The CD unit is faulty and is buried deep within the head unit itself. Best option is to replace it with a different OEM one, but it will need to be reprogrammed with a Tech2 at the dealer or similar high end scantool.

Yes the motor should move with the switch.

Did you check both fuses?

hey so im still trying to get this working how do i check the voltage and if there could possibly be a short in this circuit and what voltage and resistance should i be looking for in the switch and unit connector i have no power what so ever no mirror movement or light so i dont think im getting ...

GXP_Venom on the old forum bagged his 2005 GXP . However, he hasn't been active since 2020.

The car sits on Airbag/struts in the front and air bags in the rear, powered by a chrome air tank and twin ViAir 12V compressors in the trunk. An 8 solenoid valve air manifold controlled by a computer ...

It would be ok to push it back up into place and use some zip ties to hold it up.

Yes I still am. You can send me a PM or email @ andrew.suderman@gmail.com

Never seen a line failure, ever. I wouldn't worry about the evaporator because of the hassle involved. I would replace the condenser if you even have the slightest concern because it is pretty easy to replace.
