Started her up this morning, turned on the heat after the engine had warmed up to find nothing but cold air blowing strong through the vents.

Troubleshooting begins. Anyone else have this problem?

Yup I had this problem a few weeks ago when it started getting cold. Although mine would produce heat if I turned it to 90 let it blow heat and then turn it down to my desired temp. Now it seems to be working ok

I let mine sit at 90 for 5 minutes. Just cold air.

Hopefully it isn't the core because it's a bitch to replace.

I had a similar problem. I never changed my in cabin filter, so I started from there. After I had it apart, there were leaves and other strange looking crap in clogged in the housing. After a cleaning and install of a new filter, everything is perfect.

Hopefully, I was able to give you some help.

Was there air flowing? Just not heat?

I've never replaced the filter either.

what did you do to solve this problem?

VWNOWHONDA

sounds like a temp switch or thermostat

Alperovich

check your coolant, if u don't have enough coolant, you wont get warm air.

also, idk about the CL but other honda's have a heater/coolant valve that opens to let coolant into the heater core, it might be stuck closed.

i'd start there.

I know this is a little off topic but i have the nav 2000 tl and was wondering whether it really matters if the ac is on or off when i want heat. usually i press the off button and press 2 for he speed at the temperature at 90...... its fine but should i press the on button for the compressor or no??

does the compress even run when the heat is on??

spdy0001

Nothing

theres no need to run the compressor with the heat on unless you need to dry the air inside your car, for example, it feels stuffy or your windows are fogged up. running the AC consumes extra fuel, puts a strain on your engine and wears out your compressor faster. but you will need to run the AC compressor about 10 min every once in a while in the winter to keep the oil circulated

98K and no filter replacement?

Do you have the mugen cooling mods? I don't see it in your sig.

Either way, I'd start by replacing the thermostat, it might have just gone bad.

Heat started working again this afternoon.

Weird.

Gross huh? Probably part of the reason why I haven't done it. I'm afraid of what I might find.

Paclark01

LOL... I found some strange crap when I changed the filter.

Anyway, it was blowing cool air and it would take a while for the air to warm up enough where I could tell if the heater was working. After I changed the filter everything was excellent. The A/C works great, and the heater works great as well. I don't to have the fan up high or the temp up high to warm up the interior.

im at 120k and still on the original filter.

Just hit 97K, and heater went out.

GreenMonster

That is weird... check the coolant fluid at least... who knows what it was, but it's always good to eliminate the easy stuff...

Probably should replace the fluid anyways.

Planned on doing oil and tranny fluid this weekend.

The Cl has heat?

spdy0001

Florida has hurricanes?

Definitely sounds like a thermostat issue. If the t-stat stays open it will keep the coolant too cold to warm up, especially if its <30* outside.

My sisters regal did the same thing, it was a $5 fix.

I doubt you are low on coolant, because you would get a dummy light for that to happen.

I just got my first major issue also, both seat warmers arent working at all. Getting replaced under my 100k $0 warranty.

Dan

change mine again after 34,000 miles. $17.00 & 10 minutes is a good investment. From what my filters looked like after 34k, I am surprised you get ANY air from your vents after 98k.

Aladdin

Im having the same problem also, checked the coolant, there was basically nothing in the reservior tank, now it filled up, still no heat blowing just cool air.
