97 blazer wont engage 4 wheel drive dash lights switch but no hi or low checked two fuses on panel inside door

3 button or 4 button. If 3 button remove the pass side kick panal and diconnect the module you see there with the key on. 3 or 4 button the trucks are known for water leaks and they fill the module(3 or 4 button module are in the same place) causing all kinds of problems. What has happened to my jimmy same year was the front diff actuator ( under the battery tray) was full of transmission oil. I worked at a gm dealer as a trans tech. The front diff actuator had blown a hole in it. I have to replaced the 4wd vac switch on top of the transfer case that was where I got the oil from, also the actuator and the vacume ball behind the abs motor pack as it to was full of oil. if lucky you will not have to change your hvac control head.

Distributor

why, idk. Where, well the only way oil could be getting into you cap is if for some reason it's coming up the distributor shaft. I've worked on many distributor vechiles and NEVER came across this problem. But there is a first time for everything.

My 2000 gmc van misfires in rainy weather then clears up.

Check the inside of your distributer cap, moisture will cause major problems. Start your jimmy and run water over and around your distributer, after awhile turn it off remove the cap and feel the inside for moisture...it might not be sealing right.
