If you are not experiencing overheating problems, then it sounds like your blender vent is stuck or broken behind dash need to check and make sure that vents are changing when you change flow locations and then check blender vent door.
Sounds like your water pump has gone bad. If the water leaking seems to be dripping off crankshaft pulley, then it is your water pump. http://img88.imageshack.us/img88/4220/serppattern5sp.jpg This would cause your fan to be loose as well.
Jack up car and brace vechicle with jack stands. Then pop up hood and remove oil filer cap. Honda models use a 17mm socket or wrench for their drain plugs. The plug is at back bottom of engine. The filter is at the front lower section of engine. Then remove oil plug and washer and let drain for 10mins. Replace oil plug and washer and now remove oil filter with an oil filter wrench. Coat gasket on new oil filter with a thin layer of clean oil and twist new oil filter in place. Then put in about 4.5 quarts of oil. The accord works best on 5w-30 or 10w-30 oil. 5w for cold temps. and 10w for warmer weather. After putting in oil, let vechicle run for about 1min. then pull dipstick check level and add more oil if necessary. http://images.search.yahoo.com/images/view;_ylt=A0PDoS.xohNPo0AANG2JzbkF;_ylu=X3oDMTBlMTQ4cGxyBHNlYwNzcgRzbGsDaW1n?back=http%3A%2F%2Fimages.search.yahoo.com%2Fsearch%2Fimages%3Fp%3Dhow%2Bto%2Bchange%2Boil%2B2009%2Bhonda%2Baccord%26fr%3Dyfp-t-701%26fr2%3Dpiv-web%26tab%3Dorganic%26ri%3D2&w=450&h=600&imgurl=www.paulstravelpictures.com%2FHonda-Accord-Engine-Oil-Change-Guide%2FHonda-Accord-Engine-Oil-Change-Guide-006.JPG&rurl=http%3A%2F%2Fwww.paulstravelpictures.com%2FHonda-Accord-Engine-Oil-Change-Guide%2FHonda-Accord-Engine-Oil-Change-Guide-006.html&size=59.5+KB&name=...+for+replacing+the+motor+oil+in+the+engine+of+a+2009+honda+accord+sedan&p=how+to+change+oil+2009+honda+accord&oid=9b9fe9e20ce4ec456e4f6f9c56db964f&fr2=piv-web&fr=yfp-t-701&tt=...%2Bfor%2Breplacing%2Bthe%2Bmotor%2Boil%2Bin%2Bthe%2Bengine%2Bof%2Ba%2B2009%2Bhonda%2Baccord%2Bsedan&b=0&ni=72&no=2&tab=organic&ts=&sigr=13l84fee5&sigb=13s7idfcq&sigi=13d26i2j3&.crumb=SqzjMHUlv8u
There is probably a short or loose wire causing an arc or grounding fault. Need to follow wires off of these fuses to the lights that are going out.
You live in ohio great so do I. With our crazy weather patterns, if you want to change the coolant just go ahead and do it. Just open the petcock valve on radiator and drain what you can and put new coolant in. Not expensive and can't hurt anyway. Do once now and again during the summer and you should be fine for a long time.
From the limited info. Most likely causes are: Bad battery or bad alternator. Need to give vechicle a jump start if possible and post what happens.
Need to know if you have engine trouble codes. I can tell you this, you only have 1 catalytic converter in your vechicle. I recently worked on a 2002 escape 3.0 liter 4wd and replaced the cat. Solved the problem. When a cat. goes bad you can get sensor trouble codes all through the emission system from the back pressure and rough running at acceleration. Your cat. should be about a foot downstream from the flexpipe.
With this problem, I can give you 2 possible solutions. Your thermostat is bad and needs replaced or your heater core has plugged and no coolant can flow through. Betting on the thermostat though. Do need to know if you have overheating issues or if you can hear heater blower fan running.
If you can find a shop that sells used tires in your area and they do repair work, this type of shop will usually give you a low and fair price. One in my area took a 2002 ford escape, cut out cat and flexpipe and put new cat and flexpipe in and welded it. Parts and labor $289 dollars. You can't really beat that. A catalytic converter can not be cleaned sorry.
Take to autopart shop and have alternator tested. First, use voltmeter on battery to get a read. Then attach black end of voltmeter to black on battery and red from voltmeter to red wire coming off of alternator. Do this with car turned off. If the second read is about 0 then the fusible link is burnt out and replace it.
