How to get the back seat of 98 pontiac sunfire to let down with the latch broken?

Find yourself another 98 Pontiac sunfire somewhere, and ask the owner to let you see the mechanism, so you can repair it. You might be crawling inside the trunk and unscrewing the latch or lock in there to release it, and then finding a used pull lever somewhere, or make one from scratch. God bless your efforts.

( 1998 Pontiac sunfire ) Is it possible just to

Security light lit on the instrument cluster ? It should have anti-theft system . No , can't just remove it . It has componets - key lock cylinder housing , software programmed into control modules etc... If you just removed or disconnected the pass lock sensor the pcm -engine computer would not see a coded message ,so it would disable fuel injectors an maybe starter . Your best bet ,have a qualified repair shop diagnose it .

I have a 1998 Pontiac Sunfire with the 2.2l and I cannot figure out how to wire the starter up. This is a picture of the starter in the car now, can anyone give me advice?

The larger terminal goes straight to the battery. It looks like it does have a battery cable on it though. The smaller terminal bolt appears to have no wire on it. This is the one that switches on the starter. It should go to a solenoid or electronic box. But there has to be a wire on it going to the ignition system.

Pontiac sunfire overheating

I have your fix, Disconnect your Heater Core hoses and flush out the Heater Core or replace it. The coolant has to pass through the Heater Core before it gets to the Thermostat. GM designed the cooling system this way to speed up in-cab heating.

1998 Pontiac Sunfire GT.

If i were you i wouldn't worry about the second relay too much .because there is only one , the DRL relay !Guessing never fix's automotive electrical problems ! Testing is the name of the game , with the aid of wiring diagrams an reading an understanding how the electrical circuits work . An learning how to diagnose correctly . Basic Electricity for Service Techs Ohm law Current Flow Opens Shorts How to Use Multimeter to Troubleshoot Common Problems YouTube The Trainer 29 Understanding How Electrical CIrcuits Work and How to Test... The instrument cluster controls the headlamp systems that include daytime running lamps (DRL). The system allows the headlamps to operate at a reduced intensity when all of the following conditions apply: • The engine is running. • The transaxle is not in the PARK position. • The normal headlamps are not on. The instrument cluster turns the DRL system on by grounding CKT 592, thereby energizing the DRL relay. This action allows a reduced voltage of 6 volts to flow across the headlamps. If the vehicle has the optional fog lamps, the fog lamp relay will also be energized. The park lamps will turn on and the fog lamps will operate normally. When the headlamp switch is turned to the ON position, the instrument cluster allows normal headlamp operation. The instrument cluster also has an input from the park brake. If the park brake is in the ON position, the DRL will remain disabled until the park brake is placed in the OFF position. On vehicles with an automatic transaxle, the instrument cluster will disable the DRL until the transaxle has been taken out of the PARK position. Headlamps A rocker type switch is located on the left side of the instrument panel (IP). The rocker type switch controls the headlamps. One switch position turns on the following lamps: • The parking lamps • The side marker lamps • The taillamps • The license plate lamp • The IP lamps • The interior lamps The second switch position turns on the headlamps in addition to all of the above lamps. An IP lamp dimmer control is provided in order to vary the intensity of the IP lamps. Turn the control past the full bright detent in order to turn on the courtesy lamps. The under hood lamp is designed to turn on under the following conditions: • When the hood is raised • When the parking or headlamp switch is on You probably have a open circuit in the wiring for the passanger high beam . Your best bet would be to have a qualified repair shop check it out . May have a broken wire somewhere in the wiring harness .

I just need to know the name of the device in the steering column that controls the high/low beams and the blinker???

The dimmer switch is for high/low beams, and the turn signal switch is for the blinkers. When they are combined, it is called a multi-function switch.
