Restoring 1994 LWB.

Have replaced valve block and driver, four air bags (no leaks), four height sensors and the EAS ECU twice (two different part numbers based on VIN this year).

Can recalibrate heights but vehicle not responding to height sensors. Stuck at 28 inches to wheel arches except when rear goes to 33 on its own.

No error codes.

Only clue is left rear sensor reads 148 while others are around 80.

Plan to replace the left rear sensor and clean up contacts.

Anything else I should be replacing to get this working again?

Thanks in advance.

 

Not much interest apparently.

I will provide a follow up nevertheless.

Replacing the left rear sensor got me working air suspension.

Recalibrated fine.

Only problem is all three lights light up on occasion.

No error codes but returns to normal if non-existent faults are cleared.

Height sensor memory also resets to 5 or 250 on occasion.

Faulty eas ECU module?

Any leads appreciated.
