The C-305 connector does transistion from the outside of the vehicle to the inside behind/under the drivers seat. The problems others have had is corrosion inside the connectors (even though it is "waterproof") or pulled wires which are not making a good connection. One owner has taken numerous pictures of how he repaired the connections, the damage he found when he first took it apart, etc.
If you live in an area of the country where you drive in snow and the resulting salt useage, you are more prone to have problems with this connector, or depending on the way it was built, problems with the pulled wires.

If the ONLY thing I had put into this car was gas, I'd have 5,000 dollars in my pocket today.

Well, that noise is NOT right. I had this problem on my 2003 CXL and just had it repaired today and the sound is GONE! It is from the traction control in the rear. It must be flushed out 2 or three times by them. They flush it then they drive the car for 5 minutes in a left hand circle then 5 minutes in a right hand circle. Flush and do it again. This whole process is about $250...but if you don't do it, it will get worse and worse and when it fails its about $2500 to replace. The dealer should have a service bulliten on this (my dealer actually showed me the bulletin). My dealer at first said it was my power steering pump and they replaced that...to no avail. So then they looked it up and found the bulletin. Luckily they didn't charge me for it as I had already paid for a unneeded power steering pump so it was a wash for me.
#2058 of 2505 purge cooling system
Aug 30, 2008 (9:20 pm)
I just purchased a used 2002 Rendezvous( I swear I did not know they are lemons) and I want to clean the cooling system and install new coolant,but I need to know where the bleeders are located to purge the air out of the system. THANKS

As far as I know you only have to drain the radiator, flush, (with engine running and up to temperature) and refill with some antifreeze other than the bad stuff that GM uses. Don't worry about air in the system it will purge itself.

I believe there is 2 bleed screws for the coolant system. I just don't know where they are

Draining and Filling Cooling System
Important: Do NOT add any engine coolant supplement sealant pellets to the cooling system. Drain and refill the engine cooling system every 5 years or 240 000 km, (150,000 ml) , whichever occurs first.
1. Park the vehicle on a level surface.
2. Remove and clean the coolant recovery reservoir. Caution: To avoid being burned, do not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if radiator cap or surge tank cap its removed while the engine and radiator are still hot.
3. Remove the radiator cap when the engine is cool:
3.1. Slowly rotate the cap counterclockwise to the detention tab. Do not press down while rotating pressure cap.
3.2. Wait until any residual pressure, indicated by a hissing sound, is relieved.
3.3. After all hissing stops, press down on the radiator cap and rotate the cap counterclockwise in order to remove the cap.
Important: Recover and store used coolant in a used coolant holding tank and submit the used coolant for recycling on a regular basis. Do NOT pour used coolant down the drain. Ethylene glycol antifreeze is very toxic. Disposing of ethylene glycol into the sewer system or ground water is both illegal and ecologically unsound.
4. Place a drain pan under the radiator drain cock in order to collect all of the used coolant.
5. Open the radiator drain cock. If only partial cooling system draining is required, drain enough coolant to perform the procedure.
6. Open the air bleed valve on the thermostat housing 2 full turns.
7. Open the air bleed valve above coolant pump 2 full turns.
8. Place a drain pan under the engine block drains in order to collect the used coolant. Important: Allow the coolant to drain completely.
9. Remove both of the engine block drains.
o The front left engine block drain is located between the starter motor and the engine oil filter.
o The rear right engine block drain is located near the crankshaft position sensor.
1. Reinstall the engine block drains.
2. Close the radiator drain cock.
3. Install the coolant recovery reservoir. Notice: When adding coolant, it is important that you use GM Goodwrench DEX-COOL(R) or HAVOLINE(R) DEX-COOL(R) coolant. If Coolant other than DEX-COOL(R) or HAVOLINE(R) DEX-COOL(R) is added to the system the engine coolant will require change sooner; at 50 000 km (30,000 mi) or 24 months.
4. Slowly add a 50/50 mixture of GM Goodwrench DEX-COOL(R) or HAVOLINE(R) DEX-COOL(R) and clean, drinkable water to the radiator until the coolant level is at the base of the radiator fill neck.
5. Wait for 2 minutes and reinspect the level of the coolant in the radiator. If necessary, add coolant to the radiator until the coolant level is at the base of the radiator fill neck.
6. Install the radiator cap.
7. Ensure that the radiator cap arrow points toward the radiator overflow tube.
8. Close the air bleed valve above the coolant pump.Important: The air bleed valves are brass. Do NOT over-tighten the air bleed valves.
9. Close the air bleed valve on the thermostat housing.
10. Fill the coolant reservoir with a 50/50 mixture of GM Goodwrench DEX-COOL(R) or HAVOLINE(R) DEX-COOL(R) and clean, drinkable water. Important: If the coolant temperature indicator turns ON, turn the engine OFF immediately and allow the engine to cool. Do NOT remove the radiator cap.
11. Start the engine and allow the engine cooling fan to cycle on and off 3 times.
12. Turn off the ignition. Caution: To avoid being, burned, do not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if radiator cap or surge tank cap is removed while the engine and radiator are still hot.
13. Allow the engine to Cool.
14. Ensure that the engine coolant concentration is sufficient.

my rear bumper sensors have stopped working, any ideas how to fix them, is there a fuse or something easy I could do? thanks

I have a 2005 CXL that has had 3 new power steering pumps put in it and it continues to make the same noise each time they put a new one in. They keep insisting it is the power steering pump but have not been able to fix the problem. So far they are saying the pumps are defective. What is the bulletin you referred to on your car?

Sep 28, 2008 (9:16 pm)
I can't believe Buick will put their name behind a car that is such a piece a crap and they are not willing to fix the problems that are obviously an issue with the make and year of the car. I have had to disable the AWD or it would have cost more then $3200, the wheel bearings have had to be replaced, AC compressor, AC condenser, gasket repairs, and now I am trying to figure out why all of a sudden I have to jump my car every time I try to start it. The second the car is turned off everything goes dead. EVERYTHING. Once it is started it seems to be fine but I noticed something strange and it only happens every now and then but when I push the window buttons up every once in a while the battery light comes on and everything flashes and now my gas gauge does not work. (I hate my car) If anyone has had any similar experiences I would love to know what you had to do to fix it.
