Was the problem already diagnosed as a bad blower motor? If so then yes you will have to go into the dash to replace it. If not then start diagnostic testing with checking out your fuses and blower motor relay.

It would be nice to have a lift. Use a jack to support the engine sub frame then remove the 2 rear bolts in the engine sub frame. Then u let the jack down and the motor will be out of the way. Replace fan motor then jack the sub frame back up reinstall the bolts. Please donate next time. Gl

To replace the heater blower motor module is it required to remove or loosen the dash board?
We had the heater blower motor module replaced and a burnt connector terminal was repaired by a mechanic. When the car was returned to us the top corners of dash board ( both sides ) next to the windows at the were not seated properly. The two ends at the corners were loose, buckled and not connected to the car. The mechanic stated that it was that way before he repaired the car. We disagreed but he staed that he did not tamper with the dash board to replace the blower motor module.
Please advise

I have done all that but it will not come out. I rotated it as much as I could which is about 10 degrees but it will not come out. Do you have to remove the rubber covered insulation under floor carpet? It seems to be binding on that rubber covered insulation.

I have the carpet pulled back and it still does not rotate enough to get it out. It hangs up on the rubber covered insulation under the carpet. This rubber covered insulation extends up the firewall. Does this black rubber covered insulation have to be removed? How many degrees does it have to be rotated and in what direction?

I don't know what the problem is but I cannot get that thing out. I have been working for two days to try to get it out. I guess I will have to take it to the shop and pay big bucks to get it repaired.

Heater problem
2002 Cadillac Deville V8 Front Wheel Drive Automatic

Main/front Heater blower won't blow air, but rear blower works fine. Checked fuses and none seem blown. Don't know if it could be a blower motor or some solienod value not alllowing heater core to get warm, also tried swaping relays but nothing seems to make any difference

Cadillac Dealership took my 49.50 for Diagnosis and told me it was Blower Motor and estimated it to cost $707.23 for repair I declined as I don't have the that much money. When they returned my car the Blower and everything worked fine and is still working like new. Makes you wonder what was wrong and why they would say it was a blower motor when it in fact works like it was new.

My faith is shaken in Dealerships and there true purpose, is it to fix cars or make money from repairs that truly are unnessecary.

This Site even had a person ask if there was power to the blower motor, but no idea of where to look. That was the reason I asked the question if I knew everything I wouldn't be here asking for help would I.
A clear answer would tell the person where to look and how to test. Glad I didn't pay for this service as I can see it was no help.

I took the IP storage compartment out and everything the instructions call for. The blower housing will not turn enough or tilt enough to come out. If it can be taken out I don't know how that is accomplished. I have followed all instructions I can find on the internet and your instructions and still cannot take it out. I don't think that any of what you have sent has helped at all.
