2004 Chevrolet Express - Answered Questions & Fixed issues

I had the exact same problem with the exact same Van. I simply adjusted the throttle cable under the hood. So that instead of trying to idle around 350rpm, it is now idling between 500-550rpm. Hope this helps. *I did, at first, change the Mass Airflow Sensor and new Air filter. That seemed to help a bit, but I would still get low idle code. And it wouldn't idle until the engine warmed up. After adjusting the Throttle cable, I've had no more issues.

Check for power at the splice/connector. Also check fuses as it should have different fuses for trailer lighting. Also Try this site http://www.etrailer.com/faq-wiring.aspx. Full of useful info.

The HR arrow is the left one and the MIN arrow is on the right.

Here's the instructions from the manual:

Press and hold the HR or MIN arrow for two seconds.
Then press HR until the correct hour appears on
the display. Press and hold MIN until the correct minute
appears on the display. The time may be set with the
ignition on or off.
Hold either arrow down for two seconds and then you can adjust the hour and minutes.

Check for damaged linkage cable or the shifter it self.

Turn signal doesn't have a relay. If your talking about the flasher, it is built into the hazard switch. Which yours may or may not be in the turn signal switch. If the hazard is on the column, then it is in the switch. In the dash, it's not. I haven't worked on the express, but that's where GM puts them.
