When engaging cruise control, the dash light comes on ok, & cruise initially comes on, but after a few seconds it starts to flicker and I can hear a clicking noise in the left side foot well. Then of course cruise disengages. Does this mean that a relay is faulty, or does it indicate a possible fuse problem? Apparently, there can be vacuum hose problems, but if there was a disconnected hose wouldn't the engine run a bit rougher?

You don't have a relay hav eit scanned to see if the cruise control module is screwing up a pro will need to scan it.

I guess I should have added; I want to be able to fix this myself.
I don't have heaps of money for expensive diagnostics, and repairs.
I could have spent the $10 I sent you for gas and taken it to a pro.
That is why I went on your site. To get helpful advice, not a one line answer telling me I don't have a relay.

There isno relay in this system it runs off of a module if you think it is a relay where you hear the clicking then go to where the noise is and see if it is some type of relay, but it has nothing to do with your cruise control. When there are modules involved you HAVE to use a scanner which are thousands of dollars. The noise you are porbably hearing is the actuator itself which is on the lh side of engine compartment kicking in and out. Good luck on your repair

Well, hmac300,
I don't want to come across as a smart arse, but, I recently purchased a cruise control RELAY for $28 which is situated behind the LHS kickpanel on my Avalon.
Thankfully this has rectified the problem I initially contacted you about.
My cruise control now works fine.
Just letting you know so you can advise the next person who asks about the same problem.
By the way I also bought a OBD2 scanner for $35 which alerted me to the RELAY which didn't exist.
I'm really grateful that I'm not Thousands of dollars out of pocket.
I did my homework, maybe you should do some too.

Cheers!

Thank your for your reply, when I originally answered your question I looked on the wiring diagram and of course it didn't show a relay that is why I answered like I did. Normally those scanners only will pick up engine or trans codes. So if your check engine light goes on it will only direct you to the area an dnot much else. Thanks again. Proves our manuals aren't always correc t either.
