On my 2001 van I can just reach under the rear of the seat and pull a metal bar back to release the seat while it's still upright. If you don't have a bar, feel around underneath for a wire that will pull the two release levers up.

Do the A/C pipes going in through the fire wall get cold ( icy) ? Temp blend dood actuator possibly .Does it have A/C system in the back as well ? Auxiliary - does it get cold ?

Air Temperature Actuator
The air temperature actuator is a 3 wire bi-directional electric motor. Ignition 3 voltage, ground and control circuits enable the actuator to operate. The control circuit uses a 0-12 volt linear-ramped signal to command the actuator movement. The 0 and 12 volt control values represent the opposite limits of the actuator range of motion. The values in between 0-12 volts correspond to the positions between the limits.
When the HVAC control module sets a commanded, or targeted, value, the control signal is set to a value between 0-12 volts. The actuator shaft rotates until the commanded position is reached. The module will maintain the control value until a new commanded value is needed.
Have you hooked up manifold gauge's to check pressures ?

Did you bleed the coolant lines to let all of the air out? If there's air in the lines, you will have the issues you're describing.

You may have a defective starter solenoid due to burned main battery contacts, very common on newer gear reduction starters.

This may be related to the BCM (body control module) it can be self tested to see if any faults are present.

Make sure when you add coolant that the heater is turned on full blast and at the hottest setting. That will allow the thermostat to open and your cooling system to take more coolant.

It could be a bad fuel gauge in the dash unit, but....
Usually it's "The bad".
The fuel level sending wipe arm and windings on the fuel sender wear and send erratic readings.The only cure is a replacement fuel gauge sender.
The check engine light should not be related to the erratic fuel readings.
"The good".
If you have over 200,000kms or 120,000 miles on your van you need a new fuel pump anyway,so have a complete assembly put in which will have a new fuel sender on it.
