no left brake. . . tail light's. . . left side blink's but no brake light. . .
How can i have a turn signal with out a brake light ? it's the same wire same elements ! it's an LED Light so no dual filament to fail. . . passenger side work's perfect. . .
Could there be 2 seperate brake light switches ?

They say money can't buy happiness. It can buy old Chevy trucks though.

It's too early in the morn. I'll check my shop manual after my second cup of mud.

It's possible that there could be some grease or debris not allowing it to make contact with the leaf spring. There isn't any real way for dirt to get into the switch. You might as well buy a new one. The time put into pulling the steering wheel and figure out it can't be fixed, would be doubled if you don't have another on hand.IMHO

LIGHTS:
Left turn works
Right turn works
Both tial lights work
Right brake light works
Left brake light DOSE NOT WORK. . .
Honestly the singal switch will cause a brake light malfuntion ?
sorry for the shaken confidence just don't wanna buy somthing i don't need ! i'm over budgeted right now to many iron's in the fire so to speak. . .

GM ran the brake light thru the turn signal, if they hadn't then the brake would be on the rear lights all the time and you wouldn't have turn signal. The turn signal switch has six contacts flasher, brake, and four contacts for the rear lights. Two of the contacts for rear lights are turn and two brake. There are two leaf spring contacts one for each side, that short contacts. The brake contacts are always shorted, when signal for a turn the leaf lifts from the brake and shorts the turn. It's all in the shop manual, well in the 64 up supplement anyway. 8-)

Take out the taillight housings and clean up the rust around where the metal of the housing and the metal of the body meet. That is your ground. Use some small star washers on the screws when assembling. | | | | | Joined: May 2007 Posts: 292 Wrench Fetcher | | Wrench Fetcher Joined: May 2007 Posts: 292 | I agree with Rusty.

I got 4 LED tail light's from farm & fleet mounted in 4 new metal hanger's every thing is new there is NO rust to Clean. . . this ain't no pickup truck guy. . . as for a ground truck's chassie has been stripped and repainted so I had go threw and reground every thing even used them shnazzy star washer's stainless bolt's and such. . .the singnal switch is more than likely the problem as it's 45+ year's old along with the badly rotten cab it's in. . .I'm hopping to have a new cab this summer so this should be the last summer i gotta cruze around in a rotten cab. . .But thank's for your in put guy!
