Westie, I see you are from Oregon. Over the winter, did you fully charge the lithium ion (LI) batteries before storage? After charging, you need to disconnect the LI batteries with the red master switch (like a key) accessed thru left rear entry door above LI batteries (pg 42 of owner's manual). If you did not disconnect the LI batteries and your Ascent is under roof or covered for winter storage or temps drop below 32F, the LI batteries probably lost voltage. Also, if if you did turn off for long term storage, did you turn it back on? If the red master switch remains off, the LI batteries will not charge from the vehicle alternator, solar panels,or shore power. If all else fails, contact PW at :
for more info. Their staff and support is excellent. Hope this helps. Good luck, Ralph Ascent.
