1998 Pontiac Grand Prix GTP Q&A

1998 Pontiac Grand Prix GTP Question: I just replaced the heater core on a 98 Pontiac grand prix super charger and now

It has a ticking noise under the dashboard while driving. What could cause this? -
Answer 1
The ticking would have to be identified, Who did the work, could be an actuator, but it could be some thing not tightened, etc. That should be a hands on diagnosis. -
Comment 1
I did the work myself. I had no clue what I was doing but had a manual (Chilton) and put everything back in the reverse order as I had taken it out. It does have the theftlock radio that I didn't know was supposed to be disconnected before working under the dashboard could this be the reason? Thanks for your input. -
Comment 2
If the radio is the problem, it wouldn't work without a code being entered. If it wasn't ticking before the repair, then something was missed or it wouldn't be ticking. -
