I had the same problem with my Ranger, What i did was take a drill and in the bottom inside corner, i drilled a small hole in the houseing (not the lens) for water to dran out, and another small hole in the top of the houseing. Solved my problem. Hope this helps, cheers.

Pat Z:
This is a 'pattern' (common) failure on certain GM (and other) vehicles that I have successfully repaired many times.
The headlight assembly must be taken off vehicle. The moisture must be removed from the headlight assembly as its presence will lead to corrosion on the lamp socket fixture and, over time, delamination of the silver reflector material.
I agree with the use of a hair dryer, as suggested by Mailbox. The dryer must be used on an 'air' or 'low' setting and run until all evidence of moisture/condensation is gone. Using a 'heat' setting can melt the plastic assembly. This may take up to several hours per headlight because they have complex cavities. Shake it around after its 'blo-dry' to make certain that all moisture is gone.
The seal is leaking where the clear (front) lens mates with the assembly body (assuming there are no cracks anywhere in the plastic).
There is a 'special' RTV that is clear and called 'flowable' because of its high viscosity. It has the consistency of, say, bee honey. It is available at any auto parts store. (Do not confuse this with blue, grey or black RTV, as they will not work in this application).
Cut the top of the tapered applicator so that a fine (1/8 inch) bead can be applied. Seal the entire mating circumference. The top and bottom will each require a separate application, so that the material can set before turning over headlamp. You will note that when applying the RTV, it flows into the seal and requires no forming with a finger or tool.
The four previous posters all suggest drilling a hole in the headlight housing. I disagree with this because the additional holes allow moisture into the assembly, such as during heavy rain or from splashing ground water.
The hardest part of this job is removal and replacement of the headlight assemblies. I don't recall how the 2000 GP headlights are attached, but if adjusters have to be touched, count the number of turns required to remove a fastener so that it can be reinstalled with the same number of turns.

they either have small cracks in the lens. or either the headlight seal is dry rotted..or might be the seal on the bulb..If you don't want to purchase new light...Get a really small tiny drill bit and drill a hole at the bottom so water can drain out..releasing the moisture will prevent blowing bulbs..

your seals are gone in the headlight...dont use a hair dryer...wont solve the problem...go ahead an drill the holes...best way..use like a 1/4 bit...it need air flow to keep it dry!!..good luck !

Drilling thye hole will work, and you can even use a blow dryer to help evaporate the moisture too.
good luck
