36000 miles 2nd starter bendix not engaging, starter turns, lights everything works when it snows or very cold weather something frezzes up starter stops working like i said starter turns bendix not comming out

 

I used to have that problem with my 1967 MGB. You could get it going if you stuck your finger in the starter gear and wiggled it. Probably not practical on a Pacifica, though. It could be a lube problem with the Bendix, but first I would suspect a weak battery. If it works with a jump from a good battery, then I would definitely think about replacing the battery. If not, then I would check all the electrical connections leading to the starter for looseness or corrosion.

 

Is the starter bendix operated by a seperate wire? I ask because the starter turns

 

The Bendix engages mechanically when the starter is energized. If the starter spins without being engaged, then it's a problem with the Bendix sticking, probably due to lack of lubrication. Was the car driven through any deep water? That could cause a problem like that. Was there a warranty on that replacement starter? If so, take it back. If not, go elsewhere.
