My heat and air quit working. The blower seems to have went out. I tapped on the blower motor and it would blow pulsating at first then tapping again it went on full but went out again. Tapping again then nothing at happened at all.
Do you
have the same problem?

Hi and thanks for using 2CarPros.

If it worked when you tapped it, chances are the motor itself is bad. If you look at the first four attached pictures below, they are a diagnostic flow chart to confirm the motor is bad. Keep in mind, a damaged or corroded connection or wire can cause this type of problem too.

If you decide the motor is the problem, here is a link that shows how one is replaced in general.

Here are the directions specific to your vehicle for replacement. See the indicated pictures which correlate with these directions.

BLOWER UNIT REPLACEMENT

See Picture 5

1. Remove the glove box lower panel and disconnect the connector from it.

See Picture 6

2. Disconnect the glove box light connector and glove box mounting bolts, then remove the glove box.

See Picture 7

See Picture 8

3. Remove the right glove box side cover, the dashboard side cover and the left glove box side cover.

See Picture 9

4. Remove the glove box frame mounting bolts, then remove the glove box frame.

See Picture 10

5. Disconnect the connectors as shown.
6. Remove the blower unit mounting bolts and screws, then remove the blower unit.
7. Install the blower unit in the reverse order of removal, then make sure it runs and doesn't leak any air.
