If you hear a vacuum leak under the right side, that could be the reason there not much happening. The vacuum line comes in at the right side from the passenger compartment. Then it goes to a switching device that's electrically controlled on the automatic air system. From there hoses come out to 5 or 6 vacuum motors that pull the vanes. Any of those vacuum lines could be damaged.
You have to take off 3 or 4 little screws under the dash above the passenger's feet to get up under there. Then you need to take off four or 5 screws that hold the glovebox up. You need to be able to see through that opening to see the vacuum lines coming in.
I have a service manual so it's not as intimidating as it sounds to me.
I moved around the vacuum lines and tried to disconnect the main one. The system started working better, so one of those lines wasn't connected well or something. The dealer had been into that area with a fan motor controller problem a couple years ago and the air never seemed to blow out as well after that.
IF you have no vacuum to the controller box under there, the air should be coming out the defrost vents. That's what the system does when there's no vacuum to control it. Try feeling up there to see if you're getting air when you first start the car. Then see if it tries to move the air to other output after a minute or more of running the motor.

Lately the car surges while maintaining a constant speed or under slight acceleration anywhere from 40 to 80 mph. It seems as though the transmission can't decide which gear to be in.
I also notice a clunking metal sound while the car is in neutral or park and the revs are above 1200 RPM (such as after a cold start). I can also demonstrate the clunk if I increase the revs from idle while in neutral or park. I have seen some other posts related to these problems and am wondering if there is anything a non-mechanic can do?
Thanks for any help.
The security light comes on. If the wire breaks completely, then the car won't start because the chip can not be sensed at all.
I was hoping in 98 that flexing and breaking problem had been fixed. But the car shouldn't die from that once it's running, as I understand the setup.

Finally got windshield & trunk fixed but not the floor. I was looking for someone who had or has the same problems as I have had with their car. Mine comes up under the car when you are driving in the rain.
My sister's (formerly my mom's) '93 SSEi has never had that sort of problem, but, I do know for a fact that there were many transmission failures in the '92-'94 Bonnevilles. A friend of mine had an SSE and had the transmission replaced somewhere around 150k miles. My sister's has 117k on it.
As for the clunking, this car used to pop and "backfire" sometimes when you reved it up to a certain rpm, but I think it had something to do with a limiter to keep it from over-reving.
As for leaks, I think thats been a problem with Bonnevilles dating back to the '92 generation. the '93 we had leaked quite a bit, and my dad took some silicone and filled in around all the doors, but water would still come in, presumably from the sunroof. I had a problem with a '98 Suzuki of water coming up through the floor, and it turned out it was a plastic cap that was supposed to be filling a hole in the floorboard had come out and was allowing water to come in. Especially a pain when you go through a car wash.

1 full gallon of fuel for 45 miles = 45 m.p.g., very impressive gas mileage.
The wet area is probably air conditioning condensate, normal.
For the hard start, locate and remove the vacuum hose attached to the fuel pressure regulator. If there's any evidence of gas in the hose, replace the regulator.
If the check engine light is on have it scanned at any AutoZone (no charge) and post back with the stored trouble codes.
Do you have a second key? Try it -- if the security light on the dash is staying on. I had a problem a few times with dirt, lint, goop, on the resistor contacts not letting the reading be correct. Cleaning with pencil eraser works. But I had to try my second key.
I also had the wire to the lock cylinder start breaking strands from flexing the tilt wheel up and down. That caused the light to go on but the car still started. If the wire breaks too many strands the resistor reading to far off and the car won't start because it thinks it's being stolen.

Next, remove the spark plugs and inspect them as mentioned previously, install a cooling system pressure tester on the radiator and leave it pumped up for a few minutes, unplug the wiring harness from the ignition module, crank the engine over, look for any coolant mist coming out of the plug holes. Probably #4 and #6, rear bank driver's side. Would probably also account for the check engine light, usually code P0300, random multiple engine misfire.
The throttle body, which attaches to the upper intake plenum, has coolant passages around it to promote cold weather driveability and throttle response. The coolant passages are between the lower intake manifold and upper plenum. The EGR (exhaust gas recirculation) tube is also right there, and heat from the exhaust gases degrades and warps the plenum over time. A slight gap develops between the manifold and plenum, coolant starts leaking into the manifold, and you now have an engine which consumes coolant.
Keep driving it like that and you'll discover either A: coolant doesn't compress in cylinders and you have a bent connecting rod or wiped out rod bearing, or B: none of the engine bearings like being lubricated with coolant. Either way, you'll be looking for a replacement engine or scrapping the car if you don't get it corrected.
It had a power transistor on it and some small items. Maybe about 4 inches by 2.5 inches.

His wealth of knowledge is appreciated here.
2014 Malibu 2LT, 2015 Cruze 2LT,
Good luck.
After replacing the starter on the SSEi, never had another problem with it starting.
When accellerating normally...not lightly nor flooring it, it jerks and vibrates, she described it as running over the grooves on the interstate when you go outside your lane or when approaching an intersection that has the grooves in the pavement before you get to the stop sign. Her husband replaced spark plugs and plug wires, but the problem is still there. We always had a problem with it missing from the time we got it in '96. But, it was never as severe as she's describing it. What could it be? Any ideas?
Thanks,
Randy
Was wondering if anyone else have had the steering shaft replaced and if so, noticed any difference in the "feel".
My sister, now the owner of my mom's old '93 SSEi, was driving down an NC interstate last week when a rock was thrown from a tractor trailer, and she hear it pop the roof of the car. When she got to her destination and got out of the car, she looked at the roof, only to discover something unbelievable: The rock had hit the sunroof and shattered it. There was a bit hole right in the center of it where the rock hit, and the entire glass was shattered. She now has it oh-so-tastefully duct-taped.
How might one go about finding a replacment glass for the sunroof? Is it even possible? I wasn't sure if she'd have to go to a junk yard and get one or if she could get one from a regular glass place. Any ideas? Also, would one of those wind guards that cover the front section of the sunroof have prevented such an incident?
The garage serviced it but never changed the transmission fluid on a car with 122K???? I think I'd find another garage that would do a proper service and maintenance schedule on my car.

I just had a LOF and engine detail on my wife's 2000 Ultra. Now the DIC shows 129 psi oil pressure regardless of engine RPM. I have never seen it that high and I have never seen it rock solid unchanging. Is it possible that water from the engine detail has messed with a connection somewhere (all the other DIC indicators seem to be working okay)? Or could they have done something in the oil change to make the pressure that high?
My 04 Bonneville SLE has a gage which typically shows between 60 and 80 psi oil pressure. The gage does sweep from 0 to 120 back to 0 at startup before registering the actual pressure.
Thanks in advance for any info

Insert a flat bladed tool behind the forward upper edge of the door handle bezel.
Gently pry the upper portion of the bezel away from the door trim panel.
Pull the bezel forward over the inside door handle.
Release the retainers around the outside edges of the door trim panel.
Rock the door trim panel upwards, starting at the rear, while lifting upwards to remove.
Disconnect the door trim panel wiring harness.
Remove the armrest pull cup retainers from the inside of the door trim panel.
Use needle nose pliers to compress the 360 clip.
Pull the 360 clip out of the nylon nut on the door trim panel.
Disconnect the electrical connectors.
Remove the door control module fasteners.
Remove the door control module.
Remove the push in retainers at the upper corners of the water deflector.
Push the wiring harness through the slit in the water deflector.
Carefully peel the water deflector away from the door, being careful not to damage the butyl sealing strip.
Loosen the window retainer to window clamp fasteners 4 revolutions.
Lower the window regulator about half way down.
Disconnect the electrical connector from the power window motor.
Remove the window regulator to inner door panel fasteners.
Tilt the motor end of the window regulator to the forward end of the door.
Tilt the top of the regulator toward the lower rear corner of the door.
Remove the regulator through the front access hole in the door panel.
Kinda feels like it is being tossed around on a windy day, when the weather is fine.
Tire are new and the struts look good. GM cannot find anything wrong with it.
What have you done to fix the problem?
People often don't realize they could drive straighter if the rear is in perfect alignment. His example was where the road is grooved out by the heavy trucks damaging the pavement. When people drive there the car wants to wander a lot more than on a flat road. Align the rear and that hunting goes away to a great degree.
