If the mechanic's saying the heater is the root issue and quoting $400, here's what you need to consider—quick and clear:

🔍 First: Confirm It's Actually the Heater

Mechanics sometimes default to "replace it" when something’s just clogged or has a wiring issue. Ask:

  • "Can you show me what's wrong with it?" (Look for cracks, rust, or leaks)

  • "Is it the core, the blower, or the control module?" – $400 should be justified with specifics.

  • "Did you pressure-test it or check the thermostat first?"

💸 Second: $400 Breakdown

  • Parts + Labor? Or just the part?

  • You might get the part cheaper online and just pay labor.

  • Some vehicles make it a pain to replace the heater core (dash removal), which jacks up labor costs.

🛠️ Third: Alternatives

  • Temporary fix: If it’s leaking, bypass the heater core for now (you’ll lose cabin heat but stay mobile).

  • DIY route: If you’ve got tools and grit, replacing it yourself can cut the cost in half.

If he’s being straight, $400 isn’t outrageous—but don’t pay blind. Push for specifics, or better yet, get a second quote. Want help sourcing the part or confirming if your make/model has common heater issues? Drop the details.
