Google and find out what bulbs you need... then find the best price on the net. Order enough bulbs to replace them all. Crack open the dash panel and replace every bulb since you have it apart and call it a day... that is what I did on our 1996 Explorer.
I replaced mine with the 194 ... and I just looked up your vehicle on rockauto and they list your replacements as 194 too. They are little bulbs and you can get them just about anywhere besides the dealer.
I learned on this forum to replace all the bulbs because Murphy's law is that if you don't, then after you get the dash back together a different bulb will go out.
