94 850 High beams dont stay lit

Im thinking it's the switch.

When I turn on the headlights and pull the dash highbeams stick towards me
the highbeams go on, but as soon as I let go of the stick, they go off.

This stick also controls the cruise control, which also doesnt seem to work,
I turn the CC on and press either the up or down button at the end of the
stick, but it doesnt set the speed.

Could these both be cured by replacing the stick itself or is there
something else that is common to cause both these problems.

Thanks,

 

If my headlight switch is turned off, my headlights are on and the high
beam stalk just flashes the high beams as you describe. If the
headlight switch is turned on, my headlights are on and the high beam
stalk toggles the high beams on and off as you desire. Maybe your
headlight switch is bad.

 

My 1993 850 has a headlight relay the controls both the lo and hi beams.
It's possible that the relay itself is bad.

i have a similar problem - my CC doesnt work either.
i suspect something more involved, so when i have a little money ill visit
the Volvo dealer and get an opinion.

if your hibeam lights dont stay lit, there is a problem with your relay or
switch. Have a mechanic look at it. This is a safety item so you shouldnt
delay.

cheers!

There's a hard plastic vacuum pipe under the battery that is susceptible
to damage from battery acid/acid fumes. Replace the damaged section with
rubber hose and your cruise control will likely return to normal
operation.

Thanks Bob, I was wondering if the cruise control was vacumn driven like my
old 300zx, since I see lots of corrosion on the battery plate, chances are
you are correct and I will check tommorrow morning.

As for the headlights, well..... They work, but the lights have to be on for
about 3 to 5 seconds before the highbeams will engage. Weird huh?
