Oem alarmsystemsandgauges only work some times

how do i get my security system to work with taking it back to the dealer every timesecondly my dash gauges only works when it wants to (about 10 minutes) i have a 1998 dodge grand caravan i check all the fuses

Is it an OEM alarm system or an after market.

What has the dealer told you the problem was and how did they fix it… Well clearly they have not fixed it, only got it working again for a while.

A little more history would be nice. How often does it do this?
