What would cause no heat to blow on my 2007 honda ridgeline

The flasher relay is most likely to be the fault, check that all indicator bulbs are good as a blown bulb can cause irregular flashing pattern

The check engine light is because all check engine light codes are caused by components that affect emissions. It's not actually an engine problem, it's a problem with either your O2 sensor, MAF sensor, fuel/air ratio, pyrometer, or exhaust.

I would start with an OBDII scan, this will tell you what component is malfunctioning.

Some of these answers are confusing. On person says the sensor is near the catalytic converter, another says it's part of the engine.

I have a 2007 Honda Accord 6-cylinder, and received check engine code P0154, bank2, sensor 1.

Would this be near the catalytic converter, or would it be the first sensor on the right side of the engine (cylinder 4?)

I did drive through a puddle of water after a heavy rain (I'm guessing about 1.5 to 2 inches deep), so I'm guessing this caused it?

Thanks in advance for any advice/tips...

Change your cabin air filter. It works just like the filter in your home a/c. If its clogged it will restrict airflow.

I am having the exact same issue with my 2007 Honda Ridgeline right now...did you ever find the solution?

Rick, most vehicles had a pressure sensor to prohibit the a/c compressor from engaging unless sufficient refrigerant is contained within the system. This protects your a/c compressor from "running dry". You need to take it to someone or somewhere to have your a/c refrigerant charge checked with gauges before any further troubleshooting can be accomplished.

you may have a bad blower motor relay. this is a $5 part at rockauto.com.

you can call honda if it is the factory radio.. if you give them the vin number they should be able to help you... once you receive it you should keep it saved somewhere because every time you disconnect the battery it will reset again... sometimes you can find the code in the owners manual or sometimes you get a little card with the code on it... good luck

The 2007 Honda Accord is equipped with four wheel disk brakes. Disk brakes wear down and require regular maintenance. Worn brake pads can cause squeeling and grinding noises, as well as reduced braking power. Improperly maintained brake pads can cause damage to the brake rotors as well as brake failure. Save on labor costs by replacing your own brake pads.www.lightdeal.co.uk

It could be the wrong bulb in the brake lights/ TS
