97 Voyager electrical problems.. Please help!

hi, I have some electrical problems in my 97 grand voyager... any help would be great! I don't know if these are all seperate problems or somehow linked... :(

1. The Guages (Speedo, Temp, feul etc.) go on and off all the time. Like the whole panel is faulty... sometimes when I get frustrated and give the dash a thump, they turn on, (but not all the time)

2. The light on the radio/clock doesn't work.

3. The blower position switch for the A/C stopped working, (can't change from floor position, to face, to windscreen etc.)

4. The A/C on/off button and the one next to it always flash for the first fifteen minutes after I start the van, then goes to normal.

Pleas if anyone can help me with any of this it would be great, I can't afford to take it to an auto electrition.

Mahalo!

its a long shot but remove the battery cable for 5 to 10 min. It kinda sounds like the BCM might be going bad. Are you using the standard Plymoth key to start it ? I had this one case where the person was using a wallmart key, and when I compaired it to the standard Plymoth key the profile of the key was different. For some reason the crap key was trying to put the BCM in limp mode, When I had an original plymouth key cut the guy never had the problem again. I still dont totaly understand it but it worked and thats why I call it a long shot.
