Answers :

Sound like your instrument cluster either has a broken printed board or connections(contacts) are loose,dirty or broken contacts. You may also have loose ground to all effected gauges etc.You need to go from fuse to instrument cluster and check all wires and connections. Do you have a repair manual that has wiring diagrams. Electrical problems can take time to trouble shoot so set aside time to repair. Be prepared to disassemble dash to an extent. When doing any repairs you what to do simple tasks first.Check and see if circuits are getting power and also ground if the circuits are switched by grounds. Check your battery cables are tight. Reading through wiring diagram see if your ac, windows etc are on one circuit or the same part of your fuse box.
Sounds like you have a bear wire somewhere that if it rains or snows or wire could be wet,or loose but stays connected enough to stay charged..wiring is fautly somwhere.its not grounding out so you will not blow fuses.check for loose or corrode wires
