i suggest NOT to get the haynes manual...you pretty much have to disconnect the negative battery cable to do anything, including looking at the car from a 1/4 mile away, find a chiltons manual or get a manual from hondahookup. as far as the heating problem, first try a thermostat and bleeding the system if that doesnt work then pressure test the system and see how it is then are there leaks, ect.... windows, lube up the guides see how that does (white lithium grease) you can always go to pull a part and get some new hardware for your windows make sure nothing is cracked broken or has too much play.

im sure with some good troubleshooting and taking your time with things you can get your heat and window control back!!! g/l, hope this helped!
