Turn signals...

There are a couple issues that may be at work here. The car's 15 years old now, and is probably wearing through some things.

First, how's the volt gauge look? It should be on the larger middle line pretty much consistently. If not, you may have a charging or grounding problem. As the relay operates by heating up and releasing contacts, a lack of voltage will cause the turn signals to blink slower.

Second, it could be the relay itself. It could wear over time and eventually want replaced. I'm not sure where exactly they live on these cars as I've never had to change one.

Check the volt gauge first and if it's low, troubleshoot from there. If all that seems fine, I'd try swapping the relay.

Have you replaced the flasher unit? Also check for burned out bulbs. Lack of load ( bulb) on the turn signal unit will cause it to be slow or stay on constantly due to low current in the circuit. Also consider an electronic flasher module. A little more money but not load sensitive. Good Luck HTH StuK

all of the bulbs are working fine. As for the flasher unit, I will look into that first. Any idea where it is located?

Again, Thanks for the input.

load ( bulb)

low current

While your at it change the headlight fluid as well. ROTFL
