Hi guys.. Took my nephew for his first days beating today .. 9yrs old and into the great out doors, he loved it!! But on the journey home with 5 dogs and 3 other passengers in the motor..( Smells and misty windows), he put the read window down.. It took us 10 mins to get it back up, 1st it didn't move then when it did very slow!! Any easy solutions?? Bit of lube/wd40?? Cheers rob ps had the terrano off road quite a bit lately and an struggling to get it stuck!!!! Any ideas?
