See the awd fuse in under hood fuse box, not only check the fuse, use a test light and check voltage on fuse circuit, key on. There shows to be four park assist sensors at the rear bumper, they have three wire connector, that is ref voltage--ground--signal. You also have a rear park assist module, At the moment, I don't know where that is located? Any applicable trouble codes relating to rear park assist? I have some text explaining the operation, but, not really any troubleshooting sequence.
This is a tedious repair. The thermostat is located directly under the throttle body. When you dig down to it you will see that the lower bolt is the hardest part. Why? Because GM thought the thermostat housing was lonely. Others believe the thermostat housing looked cold. Why else would the exhaust manifold be so close lol. I am going to forward a video. It moves a little slow but the gentleman does cover the repair. Good Luck.
The blower motor is behind the glove box, sit in the passenger side seat and kick behind the glove box a few times real hard with your heat on high, the motor might kick back on, I had a Buick and the same thing happened
How long since a tune-up? Any applicable trouble codes? Is fuel your only problem? Engine cranking, you have spark at the plugs and fuel injector pulse? Your security system isn't an issue?
If the only problem is fuel, use a gage and check proper fuel pressure.
Test for control at the relay base ! With a test light connected to battery + Touch the point end to where pin 85 or 86 plugs into the fuse box . The PCM control side will turn on the test light if there is control an nothing will happen when you touch the power side ! B+ voltage will just cancel each other out The PCM just supplies a ground. Does the A/C light light when you push the button ? clutch not engaging 2005 Honda Odyssey You didn't find the problem yet ! You been working on it how long now ?
There's a youtube link that may help:
Transmission Pressure Control Solenoid PCS
You can get a pressure sensor from Ebay (but do check it is the correct one for your vehicle...). It's not a big job to change one.:
buick transmission pressure sensor
However, check the condition of your transmission fluid first. If it smells burnt or is blackish - change it.
If bearing/speed sensor assembly has been changed most lokely wiring. Use an ohm meter hooked between the two pins of the wiring harness side plug end. There will be resistance on this plug. Move/bend the wiring while the meter is hooked up and observe the reading. If the reading changes drastically or goes OL then the harness is bad. These harnesses are common problems as they flex as the wheels are turned. The dealership sells them for replacement.
Besides regular hand tools and socket sets, the first thing you will see are the front caliper retaining bolts or screws. GM cars often used large hex key fittings to loosen those, but expect anything on the caliper bolts, a lot of variation between years and models.
Your very best tool is a repair manual for the rendezvous, with step by step instructions. They cost about 26-30 dollars.
