Problems with 2004 Buick Rainier ELECTRICAL SYSTEM

Low beam lights go out when right turn signal is applied and returns to center position. a/c cooling fan does not cool compressor enough to run a/c at low speeds causing pressure to build up in feron receiver. car is at idle or low speed.

I've been having sporadic flickering low beam issues with this car since i bought it, and have spent untold hours and time trying to figure it out including taking it to the dealer. (i work nights.) last week the low beams failed on the way home from work at midnight. researched it, and finally saw the recall for gms and subsequently an ap story about widening the recall that was dated april 29. (i work at a newspaper and saw the wire story). i bought and replaced the module myself last week, and things are working well now and seem to be fixed. however, the dealer informs me that this car has not been included in the gm recall for failing headlight modules, so i can not get my money back for the module. this make and year model should be added to the recall. please be aware that other models and years than have been recently recalled, are having this issue. it truly is a safety issue and up until last week, i was always wondering when my headlights would fail. not a nice feeling when you ...

Drivers side door electrical fire - very similar to recall 15700 -fluid entered into the driver's door master power window switch module, causing corrosion that could result in a short in the circuit board, causing window switches, locks, etc to become inoperative. also resulted in an electrical fire. vehicle was unattended in a parking lot and window was open just an inch. upon return to car window was up and door would not open with remote. opened vehicle with key and noted horrible smell of electrical fire and all drivers side door electrical features were inoperative

Have noticed after a heavy and driving rain that the electrical systems acts up. we call it crazy car! all the dash lights blink & flash, bells ding and gauges fluctuate while the vehicle is at rest and on the move. we shut the engine off, sit for a minute and restart only to get the same thing. that may happen for the entire ride duration or we may get no dash lights at all. it appears to me that there is a short or a moisture that creates this happening because after a few days of good sunny weather where the water has evaporated from the roadways, our beloved rainer comes back to normal. we still experience the dimming of the headlights as we are driving at night when we are cruising with no gas pedal application at around the 32 mph marking which is rather annoying as other drivers feel as if we are flashing them. we see a down surge in the battery gauge drop for 14 volts to 11 volts and then come back up. sometimes this can happen once or twice during a 10 mile ride or as many as 50! ...

After parking my vehicle and shutting the engine off the daytime running lights did not turn off automatically. there is no switch in the cabin to turn them off and they did not turn off on their own. i had to disconnect the battery to shut the lights off and prevent the battery from draining completely. i looked at the fuses and relays next to the battery and noticed that the solid state relay number 46 controlling hdm was bulged out on one side and smelled like burnt electronics. i swapped relay 45 into the 46 position and reconnected the battery and the daytime running lamps did not illuminate with the different relay in place. i noticed the nhtsa campaign id number:14v755000, in my case it would not shut off after the relay failed. i have never reported any vehicle problems like this before but wonder if a wider recall may need to be considered.

I tried to get my car inspected today in virginia but it failed due to the dummy lights on in the dash board abs and brake. the dealer could not comm with comp but changed the fuse for the cig lighter then the codes read ebcm module fault.. in 2014 my running headlights would just go out.. no lights until i put on high beams i have had them worked on and changed but still burn out

I have an intermittent problem with my low-beam headlights not working. all the other lights work fine. both low beams will suddenly go out, but sometimes will start working again after a few minutes. other times it may take several hours before they will work. *tr

Power door locks and window locks are inoperative. have lost all power in the door locks and windows as well as the radio and the heater. i was trapped in my car this morning for about 5 minutes with the windows up and the heater was blowing out hot air. i was unable to stop that as i couldn't turn off the car or open the doors, i pried the door lock open and was able to get out of the car. *tr

Tl* the contact owns a 2004 buick rainier. the contact stated that while driving 50 mph, the speedometer failed. the contact also stated that the oil pressure light illuminated as the vehicle stalled. the vehicle was taken to a mechanic where they stated that the instrument cluster needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the failure mileage was 170,000.

My 2004 buick rainier has an issue with the electrical system where the battery keeps being drained by a dead short in the system and rendering the car useless sporadically. unfortunately, the professionals i have talked to don't seem to know the answer to the problem and i don't want to keep throwing good money after bad in my attempt to resolve it. *jb

I just bought a buick rainier 2004. i was driving it and stopped at a red light and the speedometer never went back to 0.took it to a shop and they tried to reset it . no luck . the shop told me that they have gotten a lot of them with the same problem. must have it taken out and sent to be fixed. i think this is a safety problem it its happening to a lot of cars and suvs.is their any recall on this .will their be any recalls on this .i went on line and read a lot of complaints about the same problem i am having . can you advise me what to do .thank you for your time. *tr

This is my second complaint rising from the same issue, i own two 2004 buick rainier's and they both have had an issue with the low beam headlamp bulb and connector being melted due to poor connection. this is a costly repair since the gm parts catalog does not list a replacement connector, they would rather sell the entire headlamp assembly. the first complaint occurred on my other rainier now this one. no headlamp is a safety concern, and due to the wiring overheating and melting could be a potential fire hazard.*tr

Speedometer and tachometer step motors malfunction and do not go back down upon deceleration. my speedo will show i'm doing 40 mph while stopped and sometimes peg out while driving in the neighborhood. this creates an unsafe situation with speed management in all types of driving conditions.

I have had this vehicle for 4 years and the speedometer has not worked for 2.5 years now. it will work if i reset the battery or turn the key over until the needle goes back to 0. i am told the instrument cluster is bad and i see that there are other complaints also. please help. i need to know if this is covered at a gm dealership for free. the vehicle also sputters and i have already replaced the fuel pump and had the injectors looked at. if you can please email me or contact me i would greatly appreciate it. *tr

Driving on a city street- speed limit of 35 mph my meter read 75 mph. i put my gps system on to monitor my mph. at traffic light while idling the meter read 45 mph. 2004 buick rainier had been sitting outside for 3 days with the temperature in the 20's and this was the 1st time i had driven it. tried accelerating and stopping a little suddenly hoping to jolt the meter back to normal. no results. parked for about 30 minutes, started the car and it began to register at 65 mph when driving 35 mph per gps. idling read 25 mph. after more stops and restarts the idle speed would read just below 20 mph. called onstar for a diagnostic and they connected me with gmc tech. they were going to try and reset the speedometer but found out it could not be done and wanted me to go to a local dealership. i was 400 miles from home and instead contacted my dealership at home. i was informed that this is an ongoing complaint about 2004 rainiers and that i should have no trouble traveling ...
