Re: Help with Cruise Control ! (volvowner11)

Most likely it is a vacuum problem. Underneath the battery, there is a diaphragm (I believe) with vacuum lines running to it. Replace the lines and try your cruise control again.

I have a 98 C70, probably somewhat different, but there is a cruise control module near the fuses. It's a high failure item & I bought a used one on eBay for like $50. Plug in & cruise worked!

it could also be the fuse. check ur side view mirror heater and rear window defroster. if it's anything like the 95 850, then them two and the cruise control run on the same fuse

Re: Help with Cruise Control ! (volvowner11)

My cruise control does not work either. After reading this, I removed the battery, and then the tray. There is a pump attached to the bottom side. I did not see any hanging tubes. The fuse is OK. I took a couple of camera phone pictures. There was one spot on the pump that looks like you could attach a tube. It's the white thing in the picture. Should that have a tube attached? Where would it go? If that is just an intake or something, is there a way to test if the pump is good? I can't really feel if it's working because you have to be driving 25 mph!<p>There are two very short tubes both connected to different parts of the pump... but they look OK.<p>Thanks, hopefully the pics are helpful...<p><IMG SRC="http://farm3.static.flickr.com/2437/3962709186_b76f62899f.jpg" BORDER="0"><p><IMG SRC="http://farm3.static.flickr.com/2519/3962709112_32ef992533.jpg" BORDER="0"><p><IMG SRC="http://farm4.static.flickr.com/3435/3962709040_20c3a14727.jpg" BORDER="0">
