If you're referring to the bulbs themselves, it's very easy. Pop the hood and pull up on the two white plastic tabs behind the headlight assemblies. This releases the entire headlight assembly. Remove the black rubber cover behind the turn signal bulbs and unscrew the turn signal assembly. Once that is removed, you can pull out the bad bulb and replace it with a new one.
You have to remove the tail light assembly, there's 3 butterfly nuts, I believe one of them holds the carpet up, remove that one and pull the carpet down, remove the other 2 nuts and pull
pull out the fuse
Unplug the whole light assembly from the bottom front of the car it just pops out to replace the turn signal bulb-same on the rear but you have to remove the trunk lining first.
not sure what causes it, but sometimes my signals will just not work. with lever still in position to activate signal, push button for hazards. then put signal lever in "off" position. turn off hazards. signals should work. temporarily anyway.
Push down and turn counterclockwise
The 1998 Oldsmobile Intrigue turn signal flasher control module is below the dashboard on the drivers side of the passenger compartment. The signal flasher control module should be labeled as such.
On my 1993 Oldsmobile 88, it is number "8"
Bad turn signal flasher?
I haven't checked the wiring diagram on this one, but sometimes there's a fuse for the DRL circuit and a separate fuse for the blinkers. If they are on the same fuse, you're out of luck.
If the AC is Blowing cold and turn off and on, the AC/heater control switch is bad. Replace it on eBay for around fifty dollars. Work great now.
u need a new high/low switch
Probably part of the hazard warning module - part of the hazard switch
