Default Turn signals problem

Well, I've struggled to fix this 3-4 times now. Here's the problem?:

If i turn on a turn signal or the hazards, the turn signal indicator on the dash lights up solid, doesn't flash, and no turn signal comes on, front or rear. I've checked all bulbs, so maybe it's the relay? Does anyone know where to jump the relay to check if that's the problem? Any other suggestions?

Sounds like the flasher is not getting with the program - it gets power along with the light on the dash when you engage either the turn switch or the 4 way flasher switch but rather than doing its job it locks up.

Try replacing the flasher unit - it is not a relay that you can jump because it switches to cause the flashing action.

Yep - simple - replace the flasher unit (not strictly a relay).

Just put in a new flasher at lunch. Same problem. Any more ideas?

An additional problem presented itself. When I pushed in the flasher, it pushed through the fuse block. Do I just need to detach the fuse block and reattach that piece?

It sounds like the flasher unit didn't engage electrically and pushed the connections out the back side.

You need to disconnect the battery and then unscrew the panel and pivot it back to see the rear side.

I cann't recall off hand what holds the block/connectors in place but it should be easy enough to determine once you are there.

The relay blocks are 2 part units. The front face plate part unclips and can be removed out of the panel from the front - once it is loose the rear part can be dissengaged from the panel to the rear. The fact that it pushed out suggests either the front was already loose or cracked or that the rear block tabs (4) are cracked.

Disengaging the front face plates has to be done from the rear and is one of those things that is extraodinarily hard to describe but much easier to actually do (as long as you have already done it at least once...the right tools help - I made my own)...

Given its loose it should be possible to remove the front (clips on 2 sides) - reattach to the panel & reinsert the face plate from the front of the panel. If you have cracks you need good replacement parts. I have some - not sure where else you'd get them from... certainly new may be problematic.

If all is OK it should reassemble with no major issues.

If it pushed though the panel it probably didn't connect properly (probably the same as a non-functional one).

Pulled the fuse block and reattached the flasher plug. It had just popped out, so it reattached firmly. Tried the signals with the new and old flasher and still have the same problem. Checked all relevant fuses and all are ok. I'll check all bulbs again next chance I get. Any other ideas?

Did you change any of the bulbs to LED's wihout telling us?

Have you recently changed any of the flasher bulbs?

Did you check all the fuses 14/15/36/37

Are you a robot?

Seriously, do you have these relays and fuses memorized for all MYs or do you just have a really good system of retrieving the information quickly?

Whenever I try to remember them I get it wrong - so no - its all in quick retrieval. This info is quite easy to find.

I'd still suspect a connection issue here on the relay socket. The light in the dash is fed from a different terminal on the flasher. If there is no load (no connection on the normal bulb output side) it may well not flash like this...

Pull the flasher and try connecting (jumper) the 49 & 49a terminals on the socket - turn the switch L & R - do the turn signal lights come on (obviously they won't flash).

The feed for the flasher is switch through the hazard switch... its possible there is an issue there - but less likely since that doesn't work either...

Since the dash bulb seems to activate and the flashers not - I'd be most inclined to suspect that the ground pin (31) of the flasher isn't connected correctly - you could test it...?
