I recently purchased a 99 Grand Caravan- and when I brought it home none of the cimate controls would work at all. Very quickly I realized that the battery in the van was so bad that when I got home it wouldn't start and it refused to take a charge. After replacing the battery- the fan switch worked, but none of the lights for the a/c, defrost, and rear wipers would light up or respond. Now its a situation where occasionally when I first turn on the key- they light up and function, but after hearing a relay in the fuse box under the dash either click once, or start to click repeatedy- the lights go back off. I tried to get it to go into test mode- and it starts- but after a few seconds (and that relay clicking the whole time) - all the lights go off again. I tried swapping the relay with another identical one- with the same result. Does this sound like the climate controls need to be replaced, a relay issue, or something worse. Thanks SO much for any help you can give me- this is driving me nuts (and killing me without being able to turn on my A/C in this lovely 90 degree heat).
