2005 venture electrical problem

[Bobbysommy]

put in new engine. failed inspection. they said computer has to reset itself. how do I know when it does that?

It sounds like the problem is that the computer has not run all the tests that the emissions testing station computer needs ot see. these are called I/M flags. Basically the cars computer has to run tests on all the systems and either give it a pass or fail. If the test is still listed as "Not run" then you will fail the emissions test. There are many different parameters that must be met in order for the car to run all the different tests. Basically drive the car for a few days normally, and they should all run, weather or not they pass or fail will also detemine if the check engine light comes on, and the car passes or fails the emission test.

I have several eletrical problems with my van however I have traced the problem back to the underhood fuse block it is full of corrossion and not supplying power to many components however I can not locate the part the dealer says its discontinued also the local junk yard only has a 2002 oldsmobile shilouette how ever the pins are not the same i am prepared to move the wires what do i have to do to get the new fuse block to work

Unfortunately, you will not be able to use the newer fuse block. Even though you might think you can change some pins or wire locations, you cannot change the internals of the fuse block which are completely different than your 97 model.

You are going to have to locate the proper one for your van one way or another. You might try going back to the dealership and having them do a search for any other dealer in the country that might have that part in stock still. They can do this for you when a part is discontinued and not available to order right from GM. If one is available at some other dealer, they can have it shipped to your local dealership. Otherwise, keep searching junkyards and online.

i have a 2005 chevy venture that have lost power to windows and power locks and dome lights. i can jump power in the fuse box to get the windows to move up and down. so im not getting power to the fuse box. i have went thru and redid the wires on the pass side on the floor board under the carpet. i can not find the fuse for the dome lights or the power door locks. i am at a lost. any help please.....thank you...

so, when you power up the window circuit, you are doing it at the 30A power window circuit breaker? Window circuit is an ignition switched circuit but the door locks and the dome light should be power available all the time.

the window circuit breaker gets it's power from a RAP relay in the relay block below the right side of the dash right next to the body control module. the power to the "G" circuit comes from the IGN MAIN 2 fuse, a 60A in the underhood fuse box.

the fuses for the power door locks and the courtesy lights is in the right side instrument fuse panel. CTSY LAMP fuse, 10a. PWR LOCK fuse, 20a.

While there are fuses for courtesy lamp and power door locks they are both controlled by the body control module. The RAP relay that turns on the power to the window circuit also goes into the body control module. Use a scanner and see if there are codes or if you can test the circuits you are having problems with
