Just curious if the auto climate control on my 05 Caravan buttons are all suppossed to light up. it all works fine like temp and fan speed and those indicator lights but not to where its supposed to be blowing to like head/legs, rear defrost wont illuminante with lighs on either and one of the rear wipers buttons. Its just a pain the in the butt a night but like I said most of it works and just wondering it it was normal. Thanks, Chris Bell

 

Yes they should work. Bad news is that the bulbs are not available. The only way I know of to get the bulbs is to buy a new control head or get them from a used one that still has good bulbs.

 

Just replaced my bulbs on a 2005 grand caravan. Used part#
05019519aa. They have the blue cover on the bulbs. The socket is a little tighter to twist in the circuit board but they work great.
Cost around 7$ each. You need 4 to replace them all.
