After finding the radiator relay switch under the battery in 2001 Jetta, i cannot get the plug off of the switch. There's a little tooth that the plug clips over but no way of unclipping it. Anyone have any help/ideas/tips for getting this plug off the switch?

 

go to harbor freight and purchase their pick set, usually 4 in a pack, bright colored green or orange, one pick is 90 degrees, at the base of the connector on the clip side, gently work the tip of the pick up the connector this should release the connector keep, then pull, the connector should come off the module
