Are there 2 brake light plungers for 85 vandura?

I believe both years only had on switch. A 1985 G20 van had 3 different part numbers for Brake Lite switches. This was dependent on manual trans, auto trans or trans with cruise control. A 1990 G20 van had 2 different part numbers for Brake Lite switches. None of the brake lite switch part number for the 1985 van match the ones for the 1990 van. I hope this helps...Mike

Okaaay. If the brake light switch is bad would that cause signals and hazards to not work?
