No adjustment is possible.
To operate the headlamp washers on a 2003 GMC Envoy, ensure that the vehicle is equipped with this feature, as not all models may have it. If your Envoy has headlamp washers, they can typically be activated by pulling the windshield wiper control lever towards you. This action will spray washer fluid onto the headlights. Make sure the washer fluid reservoir is filled for the system to function properly.

Fluid for my SUV (Envoy XUV) is fed from the same container that feeds the wiper fluid for the windshield.
Your switch on your steering column
its hidden under black plastic cover, three srews holding it down. its on top of windshield washer tank. so look for the fill cap for ww. pasanger side and might have a brace you need to remove to lift off cover.
They are located under the air inlet grill directly in front of the windshield. You have to remove the wiper arms and antenna to remove the grill.
There is no rear resevoir. It is fed from the large tank in the front under the air box. www.trailvoy.com All the answers for your Trailblazer or Envoy!
You don't. I had this problem on my 2002 Envoy and there was no way to clear the blockage. I tried putting the nozzle in warm soapy water and shaking it to remove the blockage, but that didn't work. I tried soaking it in alcohol and shaking it to remove the bllockage, but that didn't work. Finally I took a paper clip and worked it around inside the nozzle. No luck. Everything I did made it worse. You have to replace the nozzle.
Check with your dealership - there was a recall issued regarding the windshield wipers. They could get water in wiper motor when it rained or when the car was washed and cause the wipers not to function properly. I had an 02 with the same problem. The problem stopped after recall was fixed.
Thue insrtument fuse panel for the 98 GMC Envoy is at the drivers side just inside where the door meets the dash. The engine compartment Fuse Block is right behind the Washer Fluid Tank on the drivers side of the engine compartment.
The Envoy/TrailBlazer/Bravada etc are all a part of the GMT360 platform and share identical parts. The rear wiper is really poor on the older models. If you order a replacement kit of the 2006 wiper from www.parts4chevys.com (listed under the TrailBlazer Upgrades) that will solve the wipe issue and be a great improvement in looks also! You can see the new style wiper installed on my '03 at the enthusiasts website ..... Blazernut ....in my Gallery! For more great info on these trucks join our enthusiasts forum at www.trailvoy.com
