I cant get my blinkers to work but hazards work fine.


I need year--make--model? Sometimes there is a different flasher for turn and hazards? Have you checked applicable fuses? You may have to get at turn signal wiring and do some testing? Anytime your working on or around steering column, you need to disarm airbag, where applicable. Safety is your responsibility.

Anytime a light does something weird it's usually a bad connection. Could be a wire grounding out or a loose connection at either end of the wire.

box one in cab, and 2 in engine bay.
the HAZ fuse is marked, HAZ

ok this car can have a tail light relay. the LX dont have one.

Hazardd switch on steering column broke cant stop lights blinkin


You don't need to remove the column off to replace the hazard switch.
1. Take a pair of neede nose pliers and just pull the old one out.
2. Lube up you new one and just slide it in.
The part numbers for the hazard switch are: 15174447 (retails for $16.23) & 15177379 (retails for $18.42). You have to look for the bar code on the top of the turn signal (multifunction) switch. If the number is 26083635, 26083636, or there is no bar code use the 15174447 hazard switch. If the barcode number is 26090641, 26090642, 26096832, or 26096833 use the other hazard switch (15177379). Now these numbers came off of the recall that was for the 2000 & 2001 S/T trucks so they may not work back too far. But I know that one of those switches works back to 96 (and maybe 95).
Thank you for using Fixya and this should take you about 5 min to replace. Good luck

SERVICE ENGINE SOON LIGHT ON FRO oLDSMOBILE 2002


without knowing the trouble code that is set in memory anytime the check engine light comes on there is no way to know the problem or if there is a fix under any type of recall, there are over 200 fault codes poss in this system, have it tested for which code turned the light on.

I'm trying to find out what these codes for my car means from this diagnostic test the codes are po491, and po492?


Both are fuel injection trouble codes. Possible causes are:
  • Air pump output is blocked or restricted
  • AIR bypass solenoid is leaking or it is restricted
  • AIR bypass solenoid is stuck open or stuck closed
  • Check valve (one or more) is damaged or leaking
  • Electric air injection pump hose(s) leaking

Code 0492 means: secondary air system-bank 2, maybe the problem is there?
