2005 Chevrolet Uplander LS - Answered Questions & Fixed issues

Are you sure this is a tranny problem?? 1st thing you need to do is have a professional drive it and also run a fault code test on the Powertrain control module.

Check fuse both under the hood and inside the vehicle. Also check and cycle the headlight switch. If that does not work press the dome light off switch three times as that can lock the lights off. Good luck.

You program it using the drivers Information center (DIC)

Do you have any lights lit on the dash ? check engine , a yellow wrench, service vehicle soon etc.. These transmissions are electronically controlled ,electric solenoids inside controlled by the powertrain control module ! There is nothing you can do if you don't now about these things , take it to a shop who does ! ASE certified preferable !

more info needed...what is the question?

not knowing where you are located, do not rule out expired rodent if you are in the country....seen many in vent system

Sounds like the purge solenoid valve. Check out this website for more details. If it is the valve, the replacement will cost around $20 at any auto parts store. http://www.obd-codes.com/p0496

Back side opposite of brake rotor, has wires going to it. Looks similar to this:

don't do it. its to much work. just take the relay and use some pliers to twist the prongs don't bend but twist so they are on a 30 degree angle then push it in. this will make a good connection forever. a little dielectric grease will also help the connection

Changing the relay will fixya!

JUST BEND THE PINS ON RELAY SLIGHTLY AND REFIT

I think that system is a vacumm operated in to the switches that control your heat and vents.As simple as a hole or disconnected boot on a tiny vacuum line can cause all that.Common problem on a GM, I have an 03 pick up with similar problems and a dealer tech friend told me about it....

make up baking soda and water pour it on the terminals if corrosion is present . coca cola will also eat this corrosion. remove terminals and clean inside and out with wire brush. add dialectic grease if you have it and reinstall

I had the same water leak issue with my 2005 uplander LT. I seal around the drain tube with RTV and I actually put a flexible plastic tube on the drain at the firewall to make sure water wasn't coming in. Although this is a known common problem. It did not fix my water leak. What I found is the body seam weld at the driver's side kick panel down by the parking brake pedal was leaking. Pull the carpet back and have someone spray the windshield with a water hose and look for leaks in this area. I had to loosen the driver's side fender to pull it away enough so that I could RTV (sealant) all of the seams in that area. I have not had a water problem since.

could be a blown fuse ,check that first..

It is more than likely the heater core is leaking and needs to be replaced.....if this helps please leave rating on this post and good luck.

Take it back to the dealer and have it fixed, the charging system does have a fault.

On the firewall under the hood.

Question edited to what I think you meant to say. :>D Please always include full 'year make model'. It doesn't have a dipstick. The level is checked with a level port on the side of the transmission. The are supposed to be maintenance free. All covered in this link https://www.google.com/search?q=uplander+check+transmission+fluid ..

Are you referring to the shift cable? More details are needed to answer this
