My rear window in my 05 4runner, temporarily stops working after 4-5 "up and downs" is there a maximum limit for the amount of times one can open and close the rear window? basically, it would work for 4-5 times then when i press theh down button again on the dash it doesnt work, however if i ipress it on the keyfob, it works?? also to close it i hav to manually go to the rear with my key and hold the key to the left so it closes? THANKs!!
