Hi have you had any joy finding fault I have the same problem with my Maxus. I've replaced endless stuff even main pump ,narrowed it down to crank position sensor.but sensor is fine there should be a 5v feed but there isn't one ,checked wire back to ecu and its ok. But carnt see it being fault on ecu van drives and performs great once running. Seems to be quite a common thing on these but no one seems to have an answer, if you have any joy with yours or need any questions over it you can contact me on [email protected] for number , cheers dave

I believe it is a electric hydraulic system so maybe a bad switch or wire or hydraulics could be getting varnished and sticking

THIS IS FOR ALL 3.4 LITRE G.M. ENGINES, VENTURES MAY HAVE A 3.8 IF SO PLEASE RE-POST TO ME

I believe the shake is coming from your transmission. Please look at the fluid level and color. Also take a look at its maintenance history. When was the last time the fluid and filter was replaced? The torque converter clutch, low transmission fluid pressure, and engine issues will cause shudder (Clogged air and fuel filter, poor fuel pressure, fouled spark plugs, timing or restricted exhaust flow). Please let me know if this helps and if there is anything else. Good Luck.

Yes it can be done. look at your engine on it there will be two heater hoses coming from the engine to the heater, disconnect those two heater hoses at engine, with heater hose and two hose clamps, get the hose and clamp first at auto parts, install one end and the other end of same hose, where you disconnected the heater hoses from the engine, you have just by-pass the heater, hope this was very helpful.

Do you know how to use a wiring diagram along with a DVOM - digital volt ohm meter to test electrical circuit's ? Plus ,do you know what a BCM - body control module is ? The driver an passanger door lock switch's are just inputs to the BCM , low voltage inputs. The park neutral switch is also an input to the BCM ,that part is working - taking out of park an into park - locks & an unlocks the doors . The door switches inputs are missing ,probably . Bad ground at G302 or open in wiring . Check the flex boot from the body to the doors - Wire's like to break inside . Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. year , make , model an engine size . Under system click on body & accesories ,then under subsystem click on power door locks . With just the switches not working i wouldn't think that the BCM was the problem , but you never know . Did you disconnect the battery to clean the corrosion ? Sometimes disconnecting batteries can cause electronic modules to act up ,if you know what i mean . Battery Disconnect or Replacement Problems

A good code reader will take a "snapshot" of the vehicle computer systems when the code p0341 (camshaft sensor) is set.It may be a bad sensor or wiring or connector or computer. Most likely broken wire in harness.

Might need to replace the switch

You do not have another master ? If not you need a factory scan tool Dealer or mobile lock smith . Connect a scan tool to the vehicle. Turn ON the ignition, with the engine OFF. Insure that all power consuming devices are turned OFF on the vehicle. With a scan tool, select Request Info. under Service Programming System and follow the scan tool on-screen instructions. Disconnect the scan tool from the vehicle and connect the scan tool to a Techline Terminal with the current Service Programming System (SPS) software. On the Techline Terminal, select Service Programming System and follow the Techline Terminal on-screen instructions. Disconnect the scan tool from the Techline Terminal and re-connect the scan tool to the vehicle. With a master passkey III key, turn ON the ignition with the engine OFF. With a scan tool, select Program ECU under Service Programming System. At this point the scan tool must remain connected for the duration of the 10-minute relearn procedure. Important: On some vehicles the SECURITY telltale maybe illuminated on steady for the duration of the 10-minute relearn procedure. Observe the scan tool, after approximately 10 minutes the scan tool will display "Programming Successful, Turn OFF Ignition". The vehicle is now ready to relearn the key information and/or the passwords on the next ignition switch transition from OFF to ON. Turn OFF the ignition and wait 5 seconds. With a master Passkey III key, start the vehicle. The theft deterrent control module has now learned the key transponder information and the PCM has now learned the fuel continue password. Important: Perform this step ONLY on vehicles with EXPORT and Canadian configured theft deterrent control modules. Turn OFF the ignition and wait 15 seconds minimum. Important: Perform this step ONLY on vehicles with EXPORT and Canadian configured theft deterrent control modules. With a second master passkey III key, start the vehicle. The theft deterrent control module has now learned the second master Passkey III key transponder information With a scan tool, clear any DTCs.

https://s1.postimg.org/7nq74iahan/wiper_blade.jpg Click on the link. the picture is for wiper blade, you see the inches for each wiper above and below the blackout. To adjust the blade, if that is the problem, remove the blade and measure accordingly to measurement in picture. You may need to use a puller to remove blade. My info says a battery terminal puller should work fine, after you remove the nut. To install, my info says to torque the nut to 35 ft lbs. I found this info in my database, it's all I have to go by. Hope it helps.

Try using steel wool to clean the contacts for the door. Open the side door. See the brass pins sticking out from the door? Clean those. Then look at the plate with brass squares near the bottom of the door opening, where the brass pins would eventually make contact. Steel wool those too. Might make a couple of little sparks but don't worry. See if that helps.

General Motors did their best to confuse us shadetree mechanics! There are three locations to check. One is the passenger side fuse panel. Next is a large panel on the top of the drivers side fender under the hood. Lastly, just inside drivers door on the end of the dash. Normally the cover is somewhat triangular shaped.
Good luck!

Test the switch itself. If the switch is providing continuity look to the A/C control module for your Venture. Control Module

Belt tensioner problem or bad belt

What year is the vehicle ? The cooling fan relays have nothing to do with the temp. gauge . GM had problems with the stepper motors inside the instrument cluster . Hooking up a professional scan tool to check what the PCM - engine computer is seeing from the engine temp sensor . You have duel cooling fans controlled by three relays . Checking to see what the actual engine temp. would be the first step , checking to see if the scan tool can control the cooling fans . Look on youtube at videos on gm instrument cluster stepper motor problems

check the relays for both lights and indicators
