Blinker issues
 

So I noticed on my 2000 xj that sometimes when I use my left blinker the hazards go on in the back but sometimes they do not. On the right side, the blinker works just fine but at night the two bulbs don't stay light in the blinker when I have my head lights on but on the left side they do. I just replaced the two bulbs since last night the right blinker started blinking very fast but even with the new bulbs its still blinking fast. Checked the rear bulbs and they are not blown out. Any ideas as to what may be going on or what could be bad?

i had goofy stuff happen intermittebtly. threw a blinker module at it,,,fixed.

on our 01 the bulb socket was worn/loose and it would just start blinking fast like the bulb was blown, but it wasn't. If I bang on the housing while lit it starts blinking normal again, for awhile...

Our 99 Only does it on the drivers side, It's in the bulb socket also.

Going to try and find some tighter fitting sockets on a 98, I haven't had a problem in our 98 at all? idk lucky maybe, could have changed material supplier i'm not sure.
