When I return from the store, I stop the truck. Than I remember, I must check the mail so I turn the key and nothing happens. And I note that the MIL is not illuminated. I leave the key in the on position and lo and behold, in 30 seconds to 5 minutes, I hear a "click", like a relay has shifted, the MIL comes on and I can now start the engine.

My manuals say nothing about a relay but it sure sounds like one has reset all by itself. Any ideas what may be the problem?

Good Day!

I can't directly answer your question; in fact, I don't think there's a relay involved. Our 95s are notorious for bad ignition switches. I haven't had trouble, but I've also removed my 95s keys to their own keychains, so there's virtually no weight hanging off the ignition switch. I guess next time you might try wiggling the key, banging on that monstrosity the steering wheel / ignition key / turn signal switch stalk / etc is in, etc etc.

Good Luck & Blessings!

Don't worry about the key ring; the switch is remotely mounted from the lock.

('course, you may wear out the lock...)

Oh, no relay...

Ditto on both ^ ^ - bad Ign switch is notorious for failure, likely culprit with your symptoms - what you hear is gp controller and other stuff turning on when switch contacts eventually make connection

First of all, thank you all for your inputs. Purchased the "switch" from the local Chevy dealer for $225 + sales tax. Having the shop manuals for the truck, I felt I should be able to install the switch.

The first problem encountered was the need for a 'Snap-on' inverted torx....in fact there are 2 sizes needed. These little shooters will set you back $17 for each one!

The second problem was encounted at the end of the job; I found that I could not remove the ignition key since the key could not be rotated past the off position. Removed the key lock and re-inserted the assembly but this time, before pushing the assembly completely in, I rotated the key to the position where I could remove the key.

One other note; once the upper and lower column covers are removed, use a long 1/4 inch extension to remove both the screws hold the 2 halves of the connector as well as the screw that holds the connector to the body. Reduces the amount of time one has to lay on the back looking up.

I could not resist opening up the old switch; WOW what a complex design. There is a long cylinder which has 5 or 6 cams; each has balls and springs to assure contact. All contacts are gold plated.

I understand this general design is used in many of GM's vehicles. A local mechanic says when 100,000 miles has been reached, he finds the switch needs to be replaced. The symptoms are generally erratic behavior of the various systems; no dash lights; turning on heater blower causes the antilock light to illuminate; the cruise control operates intermittently; and in my case, stalling.
