Turn signals quit!

[Allan Broadribb]

My turn signals quit working a couple of weeks ago - then started working again - then quit again on the weekend.

The 4 way flashers still work.
The parking lights still work when the ignition is off.
All the other lights work properly.

Seems to me it is the turn signal flasher unit. I just need a confirmation before I order a new one from Pelican.

Does the flasher unit just pull out. I pulled on it but it didn't want to move so I thought I'd ask before doing any damage.

Thanks.
