could it be a problem with my blower motor resister. because my AC wont work and i cant adjust the heat i can only adjust the speed.

 

any help with that??

 

I stopped by my friends shop on the way home....he hooked up his lil computer and it was flashing Speed Sensor was out. Said to remove it first to see if there is any debris in the way before I buy a new one. I looked briefly...looks like they are about $20 give or take. I just got to find out where it is located and go to town with it!

 

Iv got a weird thing to throw into this mix

I just replaced my battery, didn't help

But I just went out plowing and sometimes when I raise the plow the abs light comes on briefly then goes back off. My speedo sometimes works, sometimes reads zero and sometimes bounces around. My cruise control and trans shifts according to what ever the needle on my speedo says, even if it's wrong.

Also my wipers will come on and off randomly, most times when I start the truck, the delay doesn't work, and if you shut them off they will stop in the middle of the window

Not sure if that's related but it all started at the same time

 

My first guess was battery, but what you are describing I would look at the Intergrate Power Module for corrosion. I understand they are open on the bottom and will get wet causing corrosion.

 

when i start my truck and dont use my blower at all my speedo will work most of the time. when i turn it on all the lights come on and ding then the speedo stops working

 

Where is the imp located? Is this the same as the PCM?

Ok new thing

So I was driving today, wiper on, and it stopped half way up the window. It actually kinda acted like a mechanical jam.... I tried to play with the switch nothing happened. Then I moved the arm an inch by hand which was hard to do....and all of a sudden it works.....it stops at the lowest part of the window correctly, the delay works again....weird


But I noticed when the wiper does move my speedo would move up about 5 mph. So while on delay the speedo would move up and down 5 mph every time the wiper moved, including me sitting at a stop light still

It also for a brief moment would flash the abs and brake lights when the blades would move

 

Bump for some help


Where is the imp located?

 

Ok so here is a new symptom

I was plowing snow, and the truck died. Now I have 1 battery and one stock alternator....so this was kinda normal considering that. But I went to recreance it, it turned over just fine, but would not start...it fired a few times then shut off. While cranking I got an error code that said. No buss. And the gauges didn't seem to work right...

I was able to get it going after 10 mins of cranking and my foot to the floor...and it plowed the rest of the night with no trouble at all



So does any of this make sense to anyone

 

Bump for a little help

Thanks guys
