Finally!! My EBCU repair was a success! I followed the video sticky that is on this site. My left rear VSS had a broken wire above the transfer case and I made a new section of the harness (soldered) with a new Delco pigtail (from Autozone) and I no longer have any fault codes or drivability trouble...

Hello again. About a year ago I was battling my 2004 Astro AWD troubles. I had a huge string of troubles (non-Astro related) that fought me that year. Those just kept coming too. I will spare the details. I HOPE that is behind me now. Back to the Astro! It has sat in my garage for the majority of th...

Wow! What a year so far. Wanted to update on my 04 Astro's status. Status is---the same. After I hurt my arm, we had area tornados Memorial Day weekend. Noting major. End of June, lost a very large tree. July, Car accident (not the Astro), and daily driver broken (again, not the Astro). Finally Star...

I have been out since my last post. I hurt myself and ended up in the ER and light duty for a couple of weeks. No further advancement on my Astro van. I will further diagnose it and update you guys during the week (I hope). I have yet to upload the squeak video to youtube. It's strange. The motor mo...

Sooo.....after repairing the exposed wires on the bank 1 sensor 1 O2 sensor, I took it for a drive. It seemed to work fairly well, but had trouble from 1st to 2nd gear. Drive it quite a bit. WOT to shift or very light throttle would also make it shift. That tells me the throttle position has an impa...

Wow! Thank you timelessbeing for the links. This is some really good information! I most certainly appreciate it!

Thank you timlessbeing. I certainly appreciate your support and help! I tried to review as much as I could while under my van (I love my van). I found a Bank 1 Sensor 1 (front driver's side) O2 sensor with two wires rubbed through. I separated and insulated them. I found the source of a gasoline sme...

Cleared my codes and went for a drive. 1st gear only in D. I can manually shift into 2nd. If I return it to D, the trans has no gear. Absolutely no speedometer now. Re-read codes and get only C0265 which is an EBCM "No signal".

Well....not my upload, but seems to have all of the same codes.

I took a short video (sound) this morning of my mystery squeak. Not sure how to upload it though. Van was cold. Squeak was present from startup. I will check the power steering pump bolts and motor mounts this weekend, if I can, and post an update.

I was correct. I had replaced the incorrect sensor. I replaced the driver's side rear sensor (VSS) this morning. Short test drive = ABS light turned off. BRAKE light turned off. SES light came on. Everything seemed to operate as it should. after less than 3 minutes, the ABS and BRAKE lights both tur...

Interesting. I'll see what I can find. I appreciate the breakdown. Yes, it will sqeak (under a load = WOT rev from idle) with the wheels not moving. The squeak seems to be coming from the lower side of the engine or transmission. I cannot locate it. It generally lessens or goes away after a good war...

I'll check my power steering pump bolts. My mystery squeak is elusive. New Belt, idler, tensioner and pulley. New water pump and fan clutch. It squeaks under load when driving or when in park and revving the engine. 240,000 miles. Original alternator and power steering pump. The squeak is present wi...

Here's an update. New wiring harness for the ignition switch. Van drove well for about 2 hours. Then....erratic speedo and funny shifting between 3rd & 4th. Different troubles than before. Also, it had developed a mystery squeak. This occurred at a low RPM and only in forward gear to begin. Just...

So, installed a VSS (transmission) and no change. Jiggled the wires (cannot remember which ones supply the 5 volts to the trans ... maybe pink? white?) and suddenly everything works. I originally had an ABS, brake, and check engine lights on. These were all also off. Yay! Until....I used my turn sig...
