Click sound

Asked by Feb 23, 2017 at 04:54 PM about the 2003 Chevrolet TrailBlazer LT 4WD

Question type: Maintenance & Repair

Well it started 2 days ago I was on the
highway and my truck was having a hard
time going over 40 and started getting
halfway hot so I took it to the shop by my
house and the test said my map sensor so
he took it off and sprayed it. This morning
on my way to work it was fine but this
afternoon when I got off work I turned my
ac on for a few minutes then turned it off
when i got on the highway and it all started
again and when I got home and shut it off I
went and turned the key to roll up my
windows and herd a click sound so I
turned the key back then back the other
way again to listen and it did it again?
Whats wrong with my baby:(

The clicking probably is a relay working, I wouldn't know what relay without looking of course, but also I would have the catalytic converter checked. It may be starting to get plugged up.


Sounds like a fan clutch. Our fan clutches have a faulty design, and will tick tick tick tick.
