1999 Oldsmobile Alero - Answered Questions & Fixed issues

The TPS sensor may be dirty or defective...be sure all tires are above 33 psi...

Sounds like the radiator is clogged. Take it to radiator shop and have it flushed

crossed wires where the conection to the heater for the window is sounds like he conected the wires wrong undo them and switch them around or follow the wires to see witch wire comes from the radio to the control panel where the buttons to tur the radio and set the defrost is ad see if the wires are crossed or in the wrong places if that dont work then it might need grounded hope that works for you

Service engine soon light is on indicating a problem with your engine. Take it to somewhere like Autozone (it is free to check code) to see what the code and problem is, then fix the problem or the light would just keep coming on every time till it is fixed.. You can use a scanner to read and reset the light, code.

There is no Am anymore only FM, you may pick up bit but nothing good!!

Take your vehicle to a qualified repair shop . Stop trying to fix something you have no clue about . If you have to ask on here an just replace a bunch of parts ,you have no business working on it

Girls like it, boys use it, parents hate it

CHECK TRUNK FUSE AND RELAY ON THE INSTRUMENT PANEL FUSE BLOCK ON DRIVER SIDE ON SIDE OF DASH PANEL.IF FUSE RELAY OKAY THE TRUNK ELECTRIC OPEN SOLENOID SWITCH BAD.THE THEFT SECURITY HAS TO CHECK AT DEALERSHIP.MOST TIME WHEN YOU HAVE TROUBLE WITH IT.YOUR KEY OR SWITCH WORN ALSO BCM CONTROL MODULE.IF DEALERSHIP FIND FAULT IN THE THEFT SECURITY SYSTEM THEY HAVE TO FIX IT AND REPROGRAM IT.NOT A HOME FIX.

the fuse panels are behind the radio, you have a shortage,, if you go to autozone it will cost nothing to get it fix

replace no 2 injector as plugs and stuff are seldom the reason for misfires dirty injectors or injector controls are generally the cause

One advantage us dealer tech's have over a week end warrior is that we have factory service repair information and have factory scan tool ,Tech 2 , to check data coming into the instrument cluster . Most of you probably don't even think about how that coolant temp infor shows up on the gauge , except by a coolant sensor ! High Temperature Indicator The high temperature Indicator function handles the control of the Engine Temperature Gauge Display and the red High Temperature indicator. The Powertrain Control Module (PCM) reads the Coolant Temperature Sensor, filters the messages, and sends the coolant temperature to the instrument cluster via a Class 2 serial data message. The PCM monitors the coolant sensor in order to determine a fault. The PCM transmits the Class 2 serial data coolant temperature report messages to the instrument cluster for the temperature gauge display and for the high temperature indicator control. The instrument cluster receives the engine temperature data in the Class 2 serial data message from the PCM. The instrument cluster converts this data into a temperature gauge pointer position which drives the gauge pointer. The instrument cluster also uses this data in order to determine the high temperature indicator control. The Body Control Module (BCM) looks for the high temperature indicator Class 2 serial data report from the instrument cluster and triggers a chime when the indicator is ON. Your best bet , take it to a qualified repair shop , rather then just replacing parts .

Unscrew the old one , screw on the new one , replace electrical connector . nothing to it . Videos on youtube if you need pictures .You need to remove the plastic engine cover if there is one .

Its possibly a dirty,or bad connection on the traction sensor. Locate the sensor, inspect and clean. Dielectric ointment helps on the electrical plug before plugging back together. Brake clean,to clean plug,sensor.

Drain plug from what?

You have a crack head or blown head gasket.

You will need to replace the multifunction switch. This will require removing the steering wheel as well as the column covers.

If it's been sitting for that long, maybe it needs FRESH gas in the fuel system,, or maybe some critters chewed up some wires under the hood..... Could be a few things

You can get a liquid dye to put in the system. You need a UV light to scan the system for the leak it will glow green

That won't help. If firing good other cylinders, then the module is good. It could be an injector problem. You need to check the spark on #1. Make sure it is sparking good, then look for air/fuel mixture problem-bad injector or something else in that cylinder affecting the air/fuel mixture so it doesn't fire good. Maybe a valve not sealing- need a compression test to check that.
