Top 20 2001 Oldsmobile Silhouette Questions & Answers

Most likely a rubber bushing......If it is leaking from the tube........it may be to full of fluid......ATF level is checked with engine running at operating temp.....Should be in the hash marks on the dip stick..........

Depending on the vehicle you could have 2 different units most suvs and vans use a front and rear u it.

Should be a 15mm

Where is your location? And if it is real cold they may not come on.

MAP manifold absolute pressure sensor may be bad .

The CLU is the compressor clutch - sounds like there may be shorted wiring in the clutch coil, causing it to draw too much current.

???????????????????????????????????????

is the light setup one ballast for high and low beam ? if so the ballast has gone, probably even the bulbs. replace the ballast and bulbs. some aftermarket ballasts don't last, if you cannot find the right ballast for replacement you will need to replace both ballasts. as every ballast set are set the same and sold in pairs.

most likely just water vapor from the heat of the cab interior cooling on the evaporator coils just like you smoke from your breath on cold mornings

Check coolant level, thermostat,could be water pump.

It's called IAC - idle air control valve > Did the RPM'S stay at 2000 or drop back down ? The PCM engine computer controls IAC valve according to engine load . Put it in gear , turn on electrical loads , headlamps , A/C etc... an the RPM raise's up so engine will not stall . More then likely the throttle plate needs to be cleaned , they get gummed up an stick at higher idle . Quick Tip Throttle Cleaning EricTheCarGuy If the IAC valve were gummed up the idle would be low or erratic . On some engines a vacuum leak will cause high idle . Videos on youtube checking for vacuum leaks .

DTC P1374 The 3X reference signal is produced by the ignition control (IC) module. The IC module calculates the 3X reference signal by dividing the crankshaft position (CKP) sensor 7X pulses by 2 when the engine is running and when the CKP synchronizing pulses are being received. The powertrain control module (PCM) uses the 3X reference signal to calculate the engine RPM and the crankshaft position at engine speeds above 1600±150 RPM. The PCM also uses these pulses to initiate injector pulses. The PCM compares the 3X reference pulses to the 24X CKP pulses and the camshaft position (CMP) sensor pulses. If the PCM receives an incorrect number of pulses on the 3X circuit, a DTC P1374 will set and the PCM will use the 24X CKP reference circuit for fuel and ignition control. The engine will continue to start and run using only the 24X CKP and the camshaft position sensor signals. Diagnostic Aids • DTC P1374 can be caused by secondary components leaking high voltage into the IC module. • Inspect for the following conditions: - Incorrect harness routing near secondary ignition components - Ignition coil arcing to wiring harness or IC module--Inspect the ignition coils for the following conditions: • Cracks • Carbon tracking • Other signs of damage - Ignition coil arcing to wiring harness or IC module--Inspect the ignition coils for the following conditions: - Secondary ignition wires arcing to wiring harness I would sugest you take your vehicle to a qualified repair shop an have it diagnosed , but i can tell that's not your way , is it . We diagnose not replace part's . Replace the IC module. Refer to Ignition Control Module Replacement . Did you complete the replacement? Go to Step 11 -- 10 Replace the PCM. Refer to Powertrain Control Module Replacement . Did you complete the replacement? Go to Step 11 If it starts an runs it's not the crank sensor behind the crankshaft pulley .

If your saying the starter motor won't crank? Make sure battery has a full charge and connections all good. Check starter wiring circuits. I'd have to make sure security system doesn't have a problem? If there is a starter relay, on load side of relay, one terminal is hot all the time, If you use jumper wire between the proper two terminals, on load side of relay, the starter should crank. If you try that, make sure tranny is in park or neutral and functional parking brake is set. With automotive relays, they have two sides, coil/control side and the other side is switch/load side that carries voltage to starter. Even if we get starter motor to crank, if security system is involved, it still won't start. If you have proper voltage and ground at the starter motor and no starter action, I'd have to check starter motor.

Hi Jodi, My name is Randy and I'm going to try and help you with your problem. Your anti-theft system is what's called PassKey this is the reset procedure.....Before you attempt this you must have a fully charged battery. 1.) Turn Ignition key to On position and attempt to start the engine, If it doesn't start release the ignition key to the On position. 2.) Security light will illuminate, Wait 10-12 minutes until it turns off. 3.) Turn the Ignition key off for 10 seconds. 4.) Try and attempt to start the engine, if it does not start, You will need to follow procedures 1-4, 3 times. Hope this helps and Good Luck, Randy.

suspect ignition switch., check fuses & relays.

If the vehicle is running an your only seeing a little over 12 volts you have a alternator or wiring problem . You should see 13.1 to 14.1 volts with the vehicle running an that could cause your strange problems . low voltage !

First check if coolant level if full. Radiator could be plugged up and corroded, due to age. Water pump worn out, does not pump much water.

Has your belt tensioner gone bad?
