Top 10 1995 Geo Prizm Questions & Answers

High and low beams use different bulbs. Both of my low beams blow out at the same time. Replace the low beam bulbs.

This is a problem that you should be able to fix. With the interior door panel there are 3 screws. 2 in the arm rest and 1 on the door handle(opener), take those out. There is a C-clip on the window crank that needs to be removed. They make a cheap little tool to remove those but I've heard people using a shop rag and removing the c clip. To remove it, turn crank to around 9 oclock then slide the tool or rag behind the crank also coming from 9 oclock. Any position will work, my point being the tool must slide in from behind the crank handle. Use a flat head screwdriver to gently pry the edges of the door panel away. There are some little clips that pop loose. It's okay if some break you can buy more. After that you will slide the door handle (opener) forward a little to pop out. Twist and turn the panel to get it over the door handle. There are 2 bolts that hold the handle on from the inside. They are 10 mm. You can reach the most forward one pretty easy but the back one is taken out through a hole in the metal door panel. Mine had a sticker over the hole with a big yellow dot on it. After that it takes some pretty good force to get the handle out of the hole. Don't be afraid to push on it. When it pops out take some wire cutters and cut the little plastic clip that holds the metal rod to the handle. The lock twists out of the hole. Now this is when you need 3 hands. Hold the new handle close to the opening and twist the lock into position. Don't attach the metal rod yet. Now actually put your key in the lock. This helps you hold the lock in the correct position while inserting the handle. Put the top of the handle in first and then the bottom should snap in next. Now from the inside, reach up and slide metal rod in the hole and rotate the plastic clip to secure it. Now the hardest thing is getting that back bolt in. It helps again to leave the key in the lock and rotate it so the bolt can secure the locking mechanism to the handle. Put the front bolt in reinstall the interior door panel and you should be in business. Good Luck

Hi there;
Somethimes this happens over time. It is usualy caused by an oil leak at or above the pully causing the rubber in the "hamonic balancer" which is part of that pully system to fail. If you don't have it repaired you will find the pully will wear through the cover behind it. So be sure to get it repaired.

Hope this helps, Good luck.

I think it is under your rear seat cushion. Remove the rear seat cushion, you'll see the gas tank cover.

I will enclose a wiring diagram to help you in checking the wiring.
Code 14 is ignition signal circuit , No ignition signal.Here are a few things to check.1} check for 5 volts signal from the ecm.2}verifies 0.10- 2.0 volt signal from (ecm) engine control module)3}check for power to distributor.4}check for open in black/orange wire between junction block no.1 and distributor or for a faulty junction block no.15}check for opens in power wire to Igniter. or a faulty ignition coil or Igniter6}check for open in red/black or black/orange wires to ignition switch and a faulty ignition switch
This problem may be a bad wire or bad ignition switch. the igniter may be bad but not to often do i see an igniter go bad.Most of the time its due to a bad ignition switch due to internal problem or bad wire connection at ignition switch. also check the wiring to distributor and to igniter.
The wiring diagram will help. hope this is helpful. good day.

Code 12 means the ECM is functioning correctly. No trouble codes stored.
Is there an actual problem with the car ?
Is the check engine light staying on ?

like 10 ways to check spark, 1 being right.(DIY)
using a real spark plug, new as a test spark plug. x4
or #2 way with a pro spark gap tool that shows the energy level
how did you do it.?

no spark at all 4 spark plugs?
some have 4 COPS. does yours, and are all 4 dead?
question 2, when did it last run, right, yesterday or 5 years ago
and were things messed with , like a new timing belt.
and that brings up, does the cams turn.? if not you skipped the 60k tune up with belt.

this car is a 1.8L 7A-FE toy engine. you can fix it the same why.
and get great help with gen7 toy forums...
when posting state country, Canada cars (geo) are different
and state what engine, 1.6 or 1.8.. i think its 1.8 if USA
in USA the EPA mandated the 1.8 in 1995. but? country ?ou never said.
the 1.8 1995 has what is called an integrated ignition assembly
it has 7/8 low voltage pins (trigger signals from ECU)
it's very unique.
96 changes are radical here in usa for OBD2 (EPA rules)
see the spark tests here. (i hate AZ but not their docs)

their logic has 1 failing , does it fail for 1 cylinder or all 4
this is the #1 logic path after checking cam spins.

Cops means DIS, Coil over plugs. and is Distributor less ignition.
the below toy idea is an odd compromise from old to new tech.
dizzy> then below oddity, then >cops. (history flow)
now MY way. (no cops, and only on this motor this year, uSA)

spark test:
1: does the twin cam spin? yes/no, if no, stop and fix that.
2: is spark timing (light) good on #1 or degrees.
yes, good, if dead skip to next
no, then the timing belt slipped, owner dont do 60k mile tunes. !!!
2: is spark dead, on 1,? only? yes, bad spark wire, or you using
a bad test spark plug, never do that, use a fresh test spark plug
and keep it in the tool box. (life time )
2a: dead one , the integrated, spark assy. is bad. 7/8 wire unit.
3:a; dead on all cylinders. (are you following me?)
bad inegrated module.
or bad inputs to it. there are 7 inputs (and ground)
no power to it. no 12v.
the inputs 7 wires are timing. if those are bad, then bingo'
then read the AZ page.

i can be, only 2 things, or both.
1: engine running way too rich.
2: dead cat.
(both happens, too)
replace the cat, might be cheaper that full engine diagnosis and repair.
in a real shop we test the cat. using up and down stream tests.
with the 5 gas analyser.
but the truth is a new CAT can hide a very filthy running motor.

on the engine near the transmission.

new spark plugs this decade. (a tune up?0
the filter is part of all 60k tuneups. letting it clog wrecks good pumps.
my wild guess, its lack of fuel flow, do to old filter.
or low fuel pressure.
car is identical to a Corolla. so is not unique or rare as some Geo cars are.
the cam belt not changes, invites valve kissing piston tops. BOOM
end of engine. (costs more to fix then worth of car)
the word is bogging, my engine bogs
if if bogs WOT (wide open throttle) and dont catch up < ITS NOT THE TPS. ever.
tps bad causes short bogs, called hesitations.
The map sensor , is what measure air flow and the ECU matches fuel to this air flow.
my guess, is it does that, but fuel pressure is like 15PSI, bad.
