As you may have heard me suggest previously, it's always a good idea -- and faster -- to do a "Search" on this Message Board. I put "cowl motor" in the subject and found several threads. To me the most interesting information came in the "Need O/H Cowl Flap Moter(Front)" thread.
There, Dale Campbell wrote that "most of the time the problem with the motors is they are full of oil and dirt and can be fixed in about an hour. I had both front and rear cowl flap motors failed. I removed both during the annual, disassembled, cleaned and put back on. They have been working fine for the last 3 years."
Jerry DeSantis added: "Dale is right. Really not much to them. Take the motor apart and clean it up. I did and only took about hour to do. Just be carefull when you remove the rotor. The brushs are held in place by a small spring and if they should come apart, then the hour becomes two."
And Sunnysky had this to say: "Our front cowl flap motor finally packed up. It had been intermittent for some time. Seems the problem was a broken brush. Spares not available but we adapted a brush from another source. Works fine now. Must have saved hundreds of dollars." (Actually, saved thousands of dollars.)
My mechanic did the same when my motor died and he saved it. He charged me $80. Sometimes it's a loose connection that needs to be soldered. Sometimes, though, all it needs is cleaning.
