GMC Jimmy ABS Light And No Brakes Live Chat: The abs warning light has been intermittently coming on in our GMC Jimmy 2000. Today the brakes completely quit working during a stop. The regular brake warning light never has/did come on. Placed vehicle in park, turned off engine, and restarted without further incident, except of the abs light continuing to light periodically. Taking the truck to have codes read, three were found. Two for the front right wheel, and on for the rear right wheel. All three pertaining to sensor failure or intermittent failure. Wouldn't there need to be something wrong besides a sensor, for the brakes to fail?
Airflow Won't Change On Chevy Lumina The heat in my 95 Lumina works but when I turn the nob to switch from defrost to the vents it doesn't switch it only blows out the defrost and on the floor a little. No matter what I turn the knob to it just comes out them places. Is it some thing to do with a vacuum line. When I turn it to air the compressor kicks but doesent blow cold air. I don't think its the knob because it makes the compressor kick on so I am confused hope you can help me.

Ignition Module Keeps Blowing Hi I was searching around and found your site and can tell you guys know what you're talking about. I have worked on cars at a dealer for 15 years and know a lot about most things, but you always get a basket case now and again. This Bonneville keeps blowing the ignition module. It came to me and the owner said a shop had already replaced the ignition module and drove the car about 2 miles and it died. They then replaced the crank sensor and the car still wouldn't start. I got the car and checked the ignition module by doing tests for the 3x and 18x crank signal checked for power and ground at the module

My 2009 Pontiac Has a Clunk Clunk noise in my 2007 Chevrolet HHR or Pontiac G6. I have a clunk noise in the front end of my HHR. It happens when i am turning the wheel, and also when going over bumps in the road. Most of the time it is when going over a set of rail road tracks.

Intake Manifold Gaskets Replaced I have a 2004 Chevy Impala LS with a 3800 6 cylinder Engine. It has 76000 miles on it and the check engine light was on. My mechanic told me that my radiator was never flushed and oil was mixing in with the radiator fluid. (Sounds to me like I had a bad head gasket). The repairs along with a serpentine belt replacement cost me over $1100 to get repaired. I started hearing a whining sound and I thought there was a bad bearing on the belt tension guide. The engine light comes back on two weeks later and it $625 to fix the EGR valve with an oil change. I asked them to check on the whining noise and the mechanic showed me was whenever the oil cap is removed, with the engine running, the whining stops. Says he never seen anything like that in the 20 years he been an ASE mechanic.

2004 Ford Taurus Wont Start I basically know the answer just need a confirmation. My neighbor helped me change my starter recently as I am disabled. Anyway the car would still only click and after reading some forums I decided that the battery cables were probably making a bad connection and should just replace the entire 2 cables. He said no and cut off a length of 1 cable and the car starts but he cut off what looks like a fusible link and he said it shouldn't even be on there and was N-rigged I told him I had bought the vehicle brand new and the factory must have done the N-rigging and even offered to take it to the nearest Ford dealer so he could argue with them. He declined.
Hyundai Elantra Overheating While my wife was driving, she heard a loud bang under the hood then water through the top of the hood. I looked at it hours later. The overflow reservoir was completely full. I checked all the hoses and couldn't find where the water was coming from. I started the car and no leaks. It didn't seem like the coolant was flowing but the car wasn't getting too hot after about 10 minutes. One fan came on. I touched the radiator cap and it was still very cool. I turned off the car and took the radiator cap off. No pressure. I added coolant then started to see steam coming up. I poured more coolant and it just flowed out of the radiator as fast as I can pour it.

Chevy Battery Dead I have a 2002 Chevy Cavalier that had an inoperable charging system. I replaced the alternator and the battery and there was no change. I soon found out that the alternator was not getting it's start signal from the PCM. I know this because I saw a diagram on the charging system and the red and gray wire that make up the connector come straight from the PCM. The red one is the alternator start signal wire! The car ran perfectly other than the charging problem before I disconnected the PCM plugs to do a continuity test on those 2 wires.
GMC Clicking In Dash I Changed actuator motor for the a/c and heater door. Question = I hear a whirring and then a click click sound in my dash. The temperature control would change from cold to hot. I was told it was the actuator motor. I replaced it with a known good one. I took the Hvac1 fuse out to reset the motor but it still doesn't work. I took the motor off of the dash and moved the control knob from cold to heat but the motor didn't rotate. Also while I had the fuse out the whirring and clicking noise did not sound. But when it is put back in the sound comes back. Any help would be greatly appreciated.

My Car Has A Check Engine Light Service vehicle soon, check engine code P0442. The intake manifold gasket was replaced about 2.5 months ago. Question = About 2 weeks ago the service vehicle soon light came on, but it would clear when car was restarted. Yesterday, dash would not light up and auto head lights would not come on immediately after car was started, but everything would start working after a few seconds. Now various warning lights will stay on and gas gauge will not work after a start, but everything then starts working after a few seconds. Now the check engine light is on with a code of P0442. These problems do not occur each time the car is started. A different combination of head lights not working or warning lights occur each time.

Oldsmobile Delta 88 Airbag Question Is there a separate sensor for the passenger side airbag on my 1998 Oldsmobile 88? In other words, if nobody is in the passenger seat does the dashboard airbag deploy anyway in an accident? Thanks. Answer: Unlike on todays newer AIRBAG systems, your car does not have a separate circuit to determine if an occupant is in the passenger seat. Anytime time there is a force sufficient to warrant airbag deployment, both airbags will deploy. This is assuming the system is functioning properly. If there were a malfunction, the warning light should be on the dash and have stored Airbag Trouble Codes. The module records data and system status before and after airbag deployment.

Car Dies At Idle With Air Conditioning On I replaced battery, resonator, fuel pump, and fuel filter. Question: I replaced the battery, resonator, fuel pump, and fuel filter on my 2005 Chevrolet Malibu Classic. Still, the engine dies when I turn on the air conditioning.

Checked for sparks at the spark plugs it was good. Didn't check all the plugs. Did the fuel spray hard or just sort of come out? Just because there is fuel there, does not mean the PSI is high enough.
