Alero

Hello! That is an extremely common issue that owners of your particular vehicle face. The window malfunction is usually caused by corrosion on the window switch. I suggest that the switch be opened and the circuit board inside of it...

The speedometer operates in correspondence to the speed sensor on the transmission. If all the other gauges are working on the dash then I would start by looking at the speed sensor on the transmission. The sensor generates a signal...

I would recommend checking for smoke coming from your exhaust. Since you are not able to find a leak and you are positive that the coolant is not mixing with the oil, it is very likely that your engine is...

If the cat monitor will not finish and pass after multiple tries then you may have a weak sensor or a catalyst (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-catalytic-converter) that is bad. I'd suggest having the vehicle scanned to test the O2 sensors for slow or...

If the problem started directly after changing these things then you need to make sure the parts you installed are the correct parts and are correctly installed (i.e. no leaks). Fuel filters are directional flow and fuel should only flow in...

It could be that you have damage to the rear strut, or maybe that the bolts that attach the lower part of the strut have loosened up and allowed the adjustment to slip. This might be a dangerous situation, so...

Hi Kevin. Thanks for contacting us today. In most cases, when the stock or OEM security system is altered (which anytime the wires are cut it is altered) it tends to create multiple electrical problems. So, it's likely that this...

Hi Jay. Thanks for contacting us today. There are several possible reasons why your Olds Alero is having these problems. While routine maintenance and service are important, it might not resolve your symptoms. Whether you can do it yourself depends...

Hi Cornelius. Thanks for contacting us today. The P-0420 typically has to do with the catalytic converter in your vehicle, but can be triggered by damaged by O2 sensors, exhaust manifold or exhaust pipe leaks, or wiring harnesses that relay...

Your vehicle has three ignition coils. Diagnostic Trouble Code P0300 (https://www.yourmechanic.com/article/p0300-obd-ii-trouble-code-random-multiple-cylinder-misfire-detected-by-jamahl-walker) relates to random cylinder misfiring (not good for the catalytic converter, by the way) which has many, many potential causes but the first thing you should consider is when...

You need to check to see if you have spark to the plugs. Scan the computer to see if crankshaft and camshaft sensors are signaling the computer to spark. If not then replace the defective spark plug (https://www.yourmechanic.com/services/spark-plugs-replacement). If it's...

This may be a sign of a weak battery, a failing voltage regulator or failing alternator. As you may know, the alternator is responsible for charging the battery while the engine runs by generating amperage and recharging the battery while...

There are two O2 sensors. One before and one after the catalyst. The one before is used for fuel control for fuel injections and the one placed after the catalyst is used to measure catalyst efficiency. A scanner will be...

Hello there, many faults will cause your 2003 Oldsmobile Alero to not start. You have done well in determining the battery needs replaced, when the battery begins to die it can cause strange intermittent electrical problems before it dies fully....

Hello. Thanks for writing in. To start, lets determine what you mean by "struggling to turn over". Does it sound like the starter is working at its prime, and the problem is with the engine? Or does the starter lag...

Radiator hose collapse is from a leaking intake manifold gasket or radiator cap is bad and not letting the system draw fluid from overflow. Replace the cap and pressure test system to see if it has a leak in the...

Hi Bridgett. Thanks for contacting us today. When a pump spins freely as you've indicated, it's usually best to replace the pump, as it's possible that damage has been done to the pump when the pulley broke.

The problem sounds like the alternator stopped charging and caused you to slowly start to loose power and then engine died and would not restart unless you jump start the car or recharge the battery. You will need to test...

Hi Emmanuel. Thanks for contacting us tonight. When you have an electrical issue like this, the first step is to determine the root source of the problem. In your case, since you are frequently blowing a fuse, its more than...

You will need to replace both of the trunk lid support shocks. They will lose their gas charge over time and will no longer support the lid weight.
