Clock problem driving me crazy

95 K2500 stock radio clock will not shut off with key out of ign. I can turn the key to acc and the clock will get brighter so I dont think its stuck in acc. I tried jiggling the ign switch like heck but the clock does'nt shut off. Funny thing, if I turn the key to the start position and slooowly turn it back the clock will shut off for about 2 seconds and then blink between 1 to 4 times I think randomly I don't know. Also if the key is out and I step on the brakes or turn the parking lights on the clock shuts off. The problem came with the truck and I recently had to replace the turn signal/cruise switch(broken hazard button) which I hoped would fix the clock too but sadly no.

Everything else works great except my right high beam (normal headlights work)

the ignition switch or the lock cylinder linkage may need adjusting or replacing. with this old vehicle I would replace the ignition switch as it is most likely very worn. not uncommon at this age for the switch to be doing this and other power issues .
