Let's check the codes. Locate the 2-pin diagnostic connector behind the glove box. I attached a pic where it should be and what it looks like.
I have attached how you check for codes. See if it makes sense to you. The big thing.....DO NOT START THE CAR!
You basically put as a jumper wire or paper clip as the pic shows...from one pin to the other. That jumps them together.
You then turn the car on to where JUST the lights on the dash come on ONLY.....DO NOT START THE CAR!
Watch your check engine light.
The first flash is the first number and the second flash it the second number. So you sit with paper and pencil and count the flashes. It will flash the same number 3 times and then go to the next if there is one. It should always start with 12. So for 12 it will be:
Flash (1) pause flash, flash (2), longer pause.... Flash (1) pause flash, flash (2), longer pause.... Flash (1) pause flash, flash (2), longer pause....
Now from this point on watch and count the other numbers. Say it is 31. It would be:
Flash, Flash, Flash (3) pause flash (1) longer pause.... Flash, Flash, Flash (3) pause flash (1) longer pause.... Flash, Flash, Flash (3) pause flash (1) longer pause....that would be code 31.
The second you see it repeating it self, then turn the car off and immediately remove the paper clip or jumper wire so you don't forget.
Again - I can not stress enough......DO NOT START THE CAR.
Let me know what the numbers are.
Great job on the pics........thanks......I attached one below.....the red circle.....that isn't a chaff mark on the wire is it?
Please check your battery ground wire and make sure it is good a tight where it connects to the car and it is clean so it does have good contact. Wiggle the wires while the car is running to see if that makes any difference. Do this to the positive wire also.
Please look at the alternator wire and make sure it has a good connection with the alternator. Make sure there is no corrosion and it is clean and tight. Wiggle the wires while the car is running to see if that makes any difference.
You said your oil pressure light blinks. I have attached info on your oil light. Has the oil been low before? Then you added? The reason is, if your oil is low and it comes one for about 5 seconds.....so the switch grounds out......even though it is okay the light will continue to flash until you turn the car off. If you are positive your oil hasn't been low, let me know about your oil being changed...your sending may be bad.
How often do you change your oil and when was the last time?
Now I am really sorry to keep asking this.....but I want to make sure I understand. You said, "My dash lights are usually always on, so I'm pretty sure at least a few of them were on at the time."
So we are saying the same thing....when you say dash lights you are not talking about when you turn your headlights on and all the lights inside are on so you can see the gauges, knobs etc. When you say dash lights you are talking about your oil light, your temp light, your check eng light.....right? Does this include the low fuel light, door ajar light, ABS light also?
Great info again on the pics....and as you think of something...like the CD player and the rear defog...I am looking at the wiring to see if all of these connect at one spot.
Please answer all of my questions above just as good as you did before - I am reviewing the wiring diagrams at this time.
Oil pressure Light Operation
The oil pressure indicator light works in two ways: it flashes continuously following a momentary loss of oil pressure, or it goes on and stays on with a complete loss of oil pressure.
When the engine first starts, before oil pressure rises above 4,3 psi, voltage is applied to the oil pressure indicator light and the oil pressure switch to ground. This tests the bulb.
With the engine running, voltage is applied at the WHT/BLU wire of the integrated control unit. With normal oil pressure, the oil pressure switch is open and the oil pressure indicator light does not come on. If the oil pressure switch closes momentarily (more than 0.5 seconds) but then opens again, the YEL/RED wire at the integrated control unit will sense ground through the switch. The integrated control unit will then provide and remove ground for the oil pressure indicator light through the YEL/RED wire. The light will flash on and off until you turn the ignition switch off. The flashing feature will not work until 30 seconds after the initial voltage is applied to the WHT/BLU wire of the oil flasher unit. This delay avoids unnecessary indicator light operation.
If engine oil pressure falls below 4.3 psi and does not increase, the oil pressure switch will stay closed. The oil pressure indicator light will then go on and stay on.
