Ok gang... I've got a good one. My interior light in the center of the cab is out and so is my power mirrors. Now everyone is going to jump and say to check fuses. Been there and done that the IOD fuse for that circuit is fine because the glovebox light and the overhead console (map lights) and cargo bed lights work. When I pulled C203 all the light went out. So power is good to that point. Now I'm trying to find S310 but the FSM lists S310 as N/S (not seen). What is weird the Cargo light in the top of the cab work. So the only thing I can figure is the S310 splice has broke loose and dropped the dome light and the power mirror on me.  Is it possible there is this G304 in the lower rear of the cab. I''ve can find nothing on G304 ground in the FSM at all.

 

 

Another view... This is for the dome light.

For the power mirrors

Trying to understand it. Is it possible a burned light bulb and bad mirror switch happened about the same time? All I can do is guess. I'm sorry.

Thats better than anything I could come up with.

Bulb is good. 

 

I can't really test the mirrors unless I pull the doors apart. It's a power issue for sure. Fuse is good. I've tested to C302 and there is power to that point. I'm starting to think its a bad ground but still can't find any documentation on G304 ground even the FSM doesn't list anything. My wiring diagrams here show the rear of the cab near the rear speaker. 

 

I've got to put back together my dash now that I know everything to that point is good. 

Now, this problem is gone. Not solved though. This morning the mirrors started working again and so did the dome light. 

 

Still never found the G304 ground. Something I've wiggled or push on made things work again. 

 So before they could change the FSM they just ganged it with another at a different location? 

 

So next time it quits leave the dome light on and wiggle or push wiring around till it comes on. Wait....you know that.

Like my little gremlins that come and go. 

 

It cooled here late last week. Ran a couple days and no surging with the ac off. So I turned the ac on and i a matter of minute it starting surging. Turned the ac off and kept surging. Pulled into a store shut it down, came back out cranked it up no surging. About an hour later I turned the ac back on and in few minutes it started surging again. Would not stop until I shut the truck off and restarted. Has not surged since. Got the ac on now just waiting to see what happens.

Dripley test your AC noise with the air conditioning turned on. Several tries might reveal something like when you try making it do it again and again.

I will have to do that and see what happens.

I took my truck out for a ride and beat the trash out of it and still the lights and mirrors work. I guess I'll just have to wait again till they quit and maybe find the loose connection. It was wild how only 2 things on that one branch of the circuit would not function but the other two would work. 

Mike,

In my manual on 8w-44-4  the center dome lamp is shown as using G201. (same ground for the headlamp switch. center dome goes through the headlight switch on the ground side.)

 

On page 8w-62-2 for the power mirrors, it uses G300 (left lower cowl. inside the cab by your left foot)  (mirror defrost uses the G201 ground......)  the G 300 is also appears that the ground for the door locks and windows.

 

hope that helps.

The two exactly I'm looking for is the ground for the power mirror movement (not heat). Then I'm looking for the ground for the dome light. Could you post a picture of what you got? @Haggar Please?!

take a peek at these.   2001 FSM

Now I've got to wait till the next time this happens. Weird part is that I've only check connectors and wiggled wires now I'm back to working again. 

I agree it is odd.  They are not really related on the ground side..... 

They share the same fuse, but radio and other obvious stuff shares it.

 

The only thing they share is C203  a connector after joint connector 5.

Joint connector 5 require for dash removal just to access that connector which is buried above the steering shaft bracket. C203 is right down at the master connector going back through the firewall.

Does anyone have the power mirror switches available? Mine isnt right at all. Blows the fuse the second you touch the switch and up is like more left/up and its all screwed up. 

Most likely the mirror motors are locked up or shorted. Or yeah it could be the switch is fubar too.

 That could also be they were cheap aftermarket mirrors and they vibrate like mad. Its so bad i drive without mirrors 90% of the time. Oh and my rearview fell off last summer and i haven't been able to get it to stick since so yea.. no mirrors haha

 

Sorry if I hijacked

Computer question Out of couriuosly... how do you post just pages of fsm?

015,

I use foxit reader pdf  printer.  (I don't use adobe acrobat or a built in browser plug in to view pdfs.)  (it is the orangish /yellowish version.  the purple is a payed subscription but has tons of features)  this gives me the flexibility to send pdf pages to a printer or just as easily to a file as a pdf.   The foxit pdf reader i am using is the free version, so I miss a lot of the options of being able to edit them and such.  If you do it often or have need for it, it is a great way to do it.  

 

I backed into it through work mainly.  Our tech manuals for the equipment we produce, I make a manual for the customer.  I keep copies of all of those by serial number.  So in a couple years when the customer calls and asks a question or emails, I can grab the exact page from their manual and send it back to them.

 

If i need to circle something in it, or draw a red arrow to point to where a possible problem is, I open it up in foxit, but then use the snipping tool (on all windows 7 and newer machines by default) that will take a "photo" of what is on your screen and save it as a Jpeg.  I can edit the Jpeg with paint and resave it with my edits on it.  

 

HTH
