I am looking to purchase some extra 2A and 5A 1/4" x 1 1/4" glass fuses for the fuse block. Should they be Fast-Blow or Slow-Blow fuses? I have a package of 20A, but it doesn't say fast or slow blow.

Always fast blow. Not much in a Chrysler wiring system will stand a high draw for any length of time. The FSM or owners manual has the spec. The fuse letter sequence will tell you what the fuse is. Most glass type are quick, and the slow ones are ceramic or composite - can't see through them.

Thanks!
 
Slow blow is usually only called for when there's a motor involved. Most anything I've ever seen on a car would be regular fast-blow fuses. Slow blow would reduce nuisance trips, fast blow would protect the system better tho.... if you get nuisance trips, find the problem and repair it. HTH, Lefty71
