Blow'n dash fuse

will not blow and the remote door locks will not work.Everything else seems
to be fine.{Yes I have disconnected the door locks seperatly and the problem
still exists.} Can that module go bad ? Like I had said in one of our
earlier talks, I had recently replaced the front axles, I was driving along
the freeway, everything was working fine for 2 days, then all of a sudden,
the dash gages stopped working and the dome light stayed on and fuse #4
blew.

Can you disconnect the remote function or door lock action module?
Also remember the 97 is famous for the ign switch problem.
I will do some more looking on it but I am running out of ideas fast.

Can That REMOTE ACTUATION MODULE BE BAD? ANY WAY TO TEST IT FOR NORMAL OPERATION?

[gmbwrenchn]

like I've said, when I DISCONNECT THE MODULE, everything works fine except the auto door locks do NOT work. CAN THAT MODULE GO BAD????

Bingo on that

If everything works but door locks with it unpluged and it is not blowing fuses the problem is in it or its circuit.
Remember a lot of stuff hooked up to it to.
The only real good way to test it with a full function body scanner or like Honda's pcm test substitute a known good one.

A good dealer or repair shop unless you want to spend a arm and leg.
3 to 5K for the good ones and another 1k year for updates.
I do not quite a Honda pcm would fit but subsitute a know good is there idea on testing.
Might be a good idea if you had a good supply of good ones.

If a module is shorting out. first unplug everything it feeds power to.

Also tool places have short finders that will led you to what ever is shorted.
Snap on and mac/ mato should have them.

I e mailed you 3 more wiring PDF on it.
It looks like the remote function actuator module feeds power to body computer on orange wire.
How many wires did you find on the plug in for remote function actuator module?

Looks like we really need to look at the vacuum actuator and the shift shaft cable. 1) How is that cable activated? I know by vacuum but what controls it's funtion? I put the Blazer up on all 4 wheels off the ground, and put it in drive. I activated 4 wheel drive hi and low. Both engage. What is the purpose of this vacuum operater shift cable which goes into the carrier assembly? It does NOT seem to be working. If the 4 wheel drive is working, what does this thing suppose to do?

Guys, it is a 1997....

REPLACE THE IGNITION SWITCH!

[gmbwrenchn]

I don't buy it.........it's something else. This thing just happens to "flip out" right after I did the front axles. Taking it in tomorrow, I've had enough of banging my head against the wall trying to figure this one out. Will report back on results.

Then you keep right on going chasing that white rabbit.

It is a 1997, it has a faulty ignition switch that will short out and blow fuses and cause numerous problems.

I gotta agree with you on this one BLT. These ignition switches can take you places that you never dreamed of. Anything connected to the ignition switch can start winking out when the switch goes bad, and no two are the same.

It was the indicator switch............ignition switch is fine. Oh well. The rabbit is back in the cage.

Any chance you might elaborate on the fix?

Who found it and how?

[gmbwrenchn]

I guess it was as simple as the indicator switch was bad. Local garage replaced the switch. Said it was bad. $17 switch, $50 labor. Figures....... it was that simple after I ripped half the car apart to look for the short. Oh well.....as many things I've have fixed myself I'm still ahead in saving myself labor cost on things. I'll eat the $67 bucks.
