1995 Ford Ranger intera light and door sounding

[sam_sam_sam]

This may not be the right place this but here it go --->

Awhile back a few month ago the itera light and the door ajar buzzer would not shut OFF
unless you remove the fuse for the itera light

There is controller that controls the following ---->
Which had bad 100uf@35 volt cap on the control boatrd

The windshield wiper speed and timing speed
The speed odotomer and the mileage meter
The itera light

More about this later----->


Then the dash light went out the dimmer controller failed the MOSFET or transiter broke lose from the board and on top that there two caps also on the board 10uf@50 volt ESR value of (3.2) the second one is 47uf@50 volts ESR value (3.7)

When it did work the dimming was not very smooth controlling the light level

Now back to other --->

The mileage meter did not work because of a bad small stepper motor the gear sheared off
got one out of the junk yard and now that working again

Taking out this dash is a real pain in the ***

So now I can see the dash in the dark and the mileage meter works and the buzzer dose not keep sounding any more

damn, that's a lot of shit - literally!
95 - is that OBD2 or pre-OBD2?

I do not known but I will find out

if it's OBD2 you could probably use a HUD display to bypass most of it.

Heh, yep. Or do what i did and get a cheap bluetooth OBDII plug and use a tablet for your HUD. Not the smartest thing, but the car had no dash! it was completely removed to get to the heater core and had to move!

How did I miss this?

I have a 1995 ranger myself. I've had and seen this problem several times. Common issue, somewhat easy fix.

There are two door switches in each door latch (total of 4 across the vehicle). They tend to get gummed up and stick, causing the problem. I suggest pulling BOTH switches and running some WD40 through them until the move a lot nicer. Consider this occasional maintenance.

FYI, One is a "door open" switch, which is the easier to access one (both are on the latch, inside the door panel). The other is a "handle pulled" switch used to turn on the dome lights if somebody pulls the handle if the door is locked, to scare off would-be thieves. In my case the latter stuck but I've read and seen both do them. They're brass mechanisms so they don't wear out... they just get gummed and stuck.

Yes it is. The ranger and explorer went OBDII in 1995. IIRC there may be a couple things not 100% OBDII compliant but for scan tool/ELM327 uses it is. It's J1850 PWM (41.6k/s) protocol like all older (pre-2008) Ford OBDII applications.

PS- yes the cluster is a slight pain to remove... I've done it several times between various LED bulb swaps, replacing busted Odometer gears (if you haven't, you'll want to the next time it's out, the ebay ones are a lot better), and modding my oil pressure gauge to true analog (pre-1987 sending unit + shorting the 20 ohm resistor near the gauge). Better than some vehicles though...

then you should clean them out with IPA or some other de-greasing solvent,
then lube them with powdered graphite - you can buy it from locksmiths.
