Ok well i had a older post about my radio wring in my car and got help and fixed it! Now i got another problem i would like to fix. My ac and heater doesn't blow air unless im driving 70 miles a hour and when im driving it barley blows. My dad knows a little bit about cars and he told me that the fans are all working so he diagnosed it as maybe needing a switch. I wanted to come here to get everyone's thoughts on this before i buy a new switch. Could it be something else that needs to be replaced?

You have a 95 grand cherokee? First thing i would do would be take the blower out. Very simple. Then put your a/c or heater on, and make sure that the fan is spinning. This way you can rule out if its the fan. Another problem you could have would be a vacuum leak, but i have not came across that problem yet so i dont know exactly which vacuum line to look for, i'm sure it could be something different but i would pull the blower out and test the speeds, and make sure it's really working.

Yeah it has to have a blower. If you google 95 xj blower you will find alot of info about how the blower works, also what the different causes of why the blower acts up.
