Had a mechanic try 2 times to fix the wipers. Didn't work, so I thought I would try and fix them myself. So I ordered the new wiper motor and I started working on it around 9:30 in the morning, figuring it would only take a couple hours at best. Well I finished around 9pm which was about 12 hours. Had no problem with the 2 bolts on top but the bottom one gave me a major headache.couldn't see under it,it was all by feel. First time I tried i dropped the bolt,couldn't find it. So I had to go to a parts store and I bought 3. Got home and dropped another one and couldn't find it. Then i dropped a 10mm socket,couldn't find it. When I finally got the lower bolt in i had been under the hood for close to 8hours. When I hooked everything back together and backed out of the garage the original bolt i lost fell out on to the floor. Still haven't seen the other bolts and socket. But the good news is my wipers work great. I'm really glad I bought this wiper motor from you.
