1983 coach rear drivers side wont raise - meltdown - 05-15-2026

Hi, I have rebuilt the six pack. installed a separate line from the raise solenoid directly to the T that feeds the drivers rear set of air bags. I engage the solenoid the air bags get hard ( no leaks) but it only raises about a 1/4". If i put a 20 ton air jack under the frame run it while concurrently powering on the lift solenoid it will lift to full height. I don't notice any binding or popping noises. Take the jack out and engage the lowering solenoid and the coach lowers. Any guidance will be appreciated. Thank You. Brion

What is the air pressure? It will take over 100 psi. Make sure you are using an accurate gauge.

Hi Richard. 110 psi, calibrated gauge. The other 3 corners raise and lower as they should.
