What owners wrote
The blower motor would work and then not work and when it worked for a long period of time, smoke would come out from under the passenger dashboard. I removed the cardboard cover and saw smoke from the connection to the blower loter and the connection was hot to the touch so I pulled it off from the blower.
Speedometer is not working. It is sticking on 15 miles per hour or sometimes 60 miles per hour. Cannot tell what speed I am going.
