However, mine works fine.

PART # 12450086 CATEGORY: Underhood Lamp PACK QTY: 1 GM LIST: $12.65
The car wash I go to when I don't have time to do a hand wash tapes down the rear blade before I go in. So obviously they had a problem with SUVs in the past. But the tape seems to do the trick, my rear blade is fine.
Anyone out there with information based on knowledge of the law care to comment on what the manufacturers obligation is??
tblazed - I think I will try to remove the light and see if I can tinker it into a working device.
What I would really like is a light like one that was in my 88 Cherokee. The hood light was on a retracting teather that was long enough to move around under the hood where-ever the light was needed. Very handy for checking fluids in poor light conditions or looking for wet spots
The owner returned the vehicle to the service department and offered valid complaints. The service department responded to these complaints, on some occasions, with “no problem found” or “could not duplicate”. It appears that no time, however, was charged for diagnosis on several complaints as evidenced on the repair orders.
Based on my experience and my knowledge of common practices in the automotive service industry, there are several guidelines which must be present prior to using a “no problem found” or “could not duplicate” response to a consumer’s complaint. These include:
- Diagnostic time must be charged to the repair order for the specific complaint – this allows the service department to show effort towards diagnosis and to comply with statutes governing repair order and invoice writing.
- Test data, whether baseline or equipment-derived, must be shown indicating the technician’s research towards the diagnosis.
- If a road test is needed, as with any drivability, engine, transmission, brake system or suspension complaint, “start” and “end” mileage must be shown.
The majority of dealership service technicians are “flat rate” technicians, who are paid by the job, not the hour. Based on the indication that no diagnostic time was charged for these complaints, I believe that a certified technician did not address each issue raised by this owner. That certified technician would have been paid for his/her time and no pay type or hours are indicated on the repair orders in question.
There are several reasons for this lack of diagnosis, involving inept diagnosis by an hourly, versus flat-rate technician, shop scheduling or apathy.

I ran across a bulletin regarding A/C performance... starts to blow warm air. See if it's related to your problem.

I agree, it is a pretty nice feature, and I wouldn't mind having one. But reading that post got me to chuckling about an article I read awhile back in one of my old issues of Auto Week where they were testing an original Hummer (also equipped with a reel light under the hood).
Evidently the Auto Week staffer who was test-driving the Hummer forgot to rewind the cord to the light prior to dropping the hood. He turned the key, heard a very loud "whiz, BANG", then spent the next two hours unwinding the cord from the fan. Oof!
I know, this was a bit off-topic, but we can all use a chuckle from time to time.
The dealer tried repairing my '02 Envoy for this problem 6 times. They replaced the ignition switch, PCM, lift gate module, throttle body, did program updates, etc., without any luck. The stalling would usually occur when the engine was halfway warmed up, usually when stopped at a long traffic light. It would do it less often when fully warmed up. Sometimes I would get those messages on the DIC, other times no messages, and sometimes the SES would light.
Keep all your repair paperwork, and make sure you document the problem the same way every time you take it in for repair. GM ended up buying back my Envoy in April. Good luck.
Your AC may just need a recharge of cooling fluid.

When I turn off the engine and restart the problem goes away and doesn't reappear.
Does anyone know the bulb number for the rear stop light? My left stop light is blown out and I want to replace it. I know its probably in the manual but I figured I would ask since I'm at work and have access to the computer
I went to start up the TB while I had the AC button
depressed. I did not hold the key in the start position long enough and the TB acted like it wanted to start but did not make it. We have all done this once or twice. Then without turning the vehicle to the off position I turned the key to start again and the vehicle started. (note this was not a case of the vehicle not wanting to start but a case of a lazy hand on my part when I bumped the starter).
At this point in time the AC never would get cold. I went through OnStar and everything to figure out why the AC quit on me when it had been working on my trip to the store.
This is when I remembered what a former shop foreman turned salesman told me regarding the recirc/AC function on my Silverado. If the vehicle is already running and you bump it into the start position, the relay for the AC will shut off and stay that way until the next ignition off/on cycle.
I stoped the TB and restarted it, low and behold the AC started working...
Hope this helps.
Brake Lights
They are 3157's used in the TB. (3057 in the Envoy)
After my 6th attempt i filled out the paper work for lemon law and mailed it to GM. The lady from GM called me today and the has set up a final appointment with the dealer for fixing the a/c on Tuesday 6/17/03. Will keep you posted as to what happens,if they fix it fine if not they will have to buy my TB back.
A/C Compressor Clutch Operation
The following conditions must be met in order for the A/C compressor
clutch to turn on:
-Ambient air temperature above 4°C (40°F)
-A/C low pressure switch signal circuit is grounded
-A/C refrigerant pressure sensor parameter is less than 2957 kPa (429
psi)
-A/C compressor temperature switch contacts are closed
-PCM receives an A/C request from the HVAC control module
-Engine coolant temperature (ECT) is less than 121°C (250°F)
-The engine RPM is more than 550 RPM
-The throttle position is less than 100%
The sensor information is used by the PCM to determine the following:
-The A/C high side pressure
-An A/C system load on the engine
-An excessive A/C high side pressure
-The heat load at the A/C condenser
Once engaged, the compressor clutch will be disengaged for the following
conditions:
-Ambient air temperature is less than 4°C (40°F)
-A/C compressor temperature switch contacts are open
-Throttle position is 100%
-The A/C low pressure switch is open
-A/C high side pressure is more than 2957 kPa (429 psi)
-A/C low side pressure is less than 151 kPa (22 psi)
-Engine coolant temperature (ECT) is more than 121°C (250°F)
-Engine speed is more than 5500 RPM
-Transmission shift
-PCM detects excessive torque load
-PCM detects insufficient idle quality
-PCM detects a hard launch condition
The A/C compressor is protected from overheating by the compressor
temperature switch, which is mounted at the rear of the A/C compressor.
The switch is wired internally to the compressor and is not serviceable.
The switch opens and disengages the compressor clutch when temperatures
reach 135°C (275°F). The switch closes when the compressor temperature
cools to 120°C (248°F).
A/C compressor clutch will not engage under the following conditions:
-The A/C high side line pressure is over 2957 kPa (429 psi).
-The A/C low side line pressure is under 151 kPa (22 psi).
-Throttle angle is at 100 percent.
-Engine speed is more than 5500 RPM.
-Engine coolant temperature (ECT) is more than 121°C (250°F).

Copy and paste the Japanese URL page into the "Translate a Web Page" space and select Japanese to English. Don't know if it's any more obvious what he's doing but the translations are certainly entertaining..
Looks like he's rigging in brighter tail-brake type lamps. More current, heat, and maybe failure would be my guess as to the long term results.

12450086 is avalible from GM and is NOT discontinued.
Not a bad looking vehicle. I like the rear bumper and hatch setup on it.
Anyone have the Borla system? sound like a Mustang GT or some other sports car? cost?

Yes

TBlazed thanks for the research into the complexity of the AC mechanism. Yet all the conditions there look logical and reasonable, just makes for complicated circuitry to work right.
simutaneously to determine what to deliver.
Most folks working in a modern manufacturing plant see these type of logic trees often
