2001 E320 PSE troubleshooting woes
Hello it is time for me to fix my PSE troubles. It has been almost a year without my Comfort Seats! My back can't take it anymore.. LOL
I have read and read and read and cannot find any help so here it goes.
I have a W210 2001 wagon rear wheel drive. When I got it everything worked work fine. Somewhere along the way I lost my my pressure and vacuum. It might have been when I hit a deer on the passengers front. From what I understand there is a vacuum Reservoir there.
Current stats:
The the door locks only work manually, the key fob makes the windows roll up and down and the alarm works, that is all. The Dash door lock button does nothing. The tailgate does not lock the fuel door does not lock Etc. When you turn on the ignition, The pump does the normal 3 second cycle and then shuts off.. I know there is a vacuum leak under the dash, I can hear it., my vents change all the time even if sitting in park with the air conditioning on. There is 0 moisture in the battery and PSE area. All fuses are good.
Question, if I remove the vacuum line at the back of the intake on my engine and put a hand vacuum pump on it,, should it hold vacuum?
Does anyone have a sequence of operations for the PSE system? It seems like it does the 3-second start up and then shuts off like it's waiting or has been interrupted. I would highly doubt there's anything wrong with my pump.
any suggestions or communication about this would be greatly appreciated! My back is killing me! I drive cross-country several times per year LOL.
Thank you.
