The locks open....the handles won’t budge to open the doors.
I just read on line to use a d-icer like one usd on windshield.....or make one of alcohol and water. I have both so I’ll try those.
There was a time I got a letter my extension cord and went to the car with a hair dryer to warm up the handle enough to get it open.
I’ve also had cases where the driver side was frozen shut, but was able to get the passenger side open and scoot over.
I’ve used a hair dryer before. Hit and miss. Just be careful. I gave my driver door a try day before yesterday and it opened right up!! Great — EXCEPT the gasket came with the door and I couldn’t get that pot-licker to stay in place for love nor money. So there’s an air leak until it warms enough to soften it up.
